Description of problem: PLEASE NOTE, not REGEXP but REGEX.H Trying to build universal-ctags from source I get this error checking if regcomp works... no configure: error: regcomp() on this system is broken. I look at the configure file and see this code: #include <sys/types.h> #include <regex.h> int main(void) { regex_t patbuf; return (regcomp (&patbuf, "/hello/", 0) != 0); } I created a simple regcomp.c file, compile it with gcc -g -Wall -o zzz regcomp.c I get coredumps Version-Release number of selected component (if applicable): Linux localhost.localdomain 4.18.17-300.fc29.x86_64 #1 SMP Mon Nov 5 17:56:16 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux How reproducible: Steps to Reproduce: 1. compile the sample program above 2. run it, it core dumps Actual results: /fdev/universal-ctags/zzz Missing separate debuginfos, use: dnf debuginfo-install glibc-2.28-17.fc29.x86_64 Program received signal SIGSEGV, Segmentation fault. 0x00007ffff7dff40a in __libc_start_main () from /lib64/libc.so.6 (gdb) bt #0 0x00007ffff7dff40a in __libc_start_main () from /lib64/libc.so.6 #1 0x000000000040107e in _start () Expected results: compile and pass regex tst Additional info: environment _=*20379*/usr/bin/env BASH_ENV=/usr/share/Modules/init/ksh CC=/usr/bin/gcc COLORFGBG=default;default COLORTERM=rxvt-xpm COMP_KEY=0 COMP_POINT=0 COMP_TYPE=0 CXX=/usr/bin/g++ DESKTOP_STARTUP_ID=i3/i3-sensible-terminal/566-126-localhost.localdomain_TIME530937447 DISPLAY=:0 EDITOR=nvim ENV=/usr/share/Modules/init/profile.sh F77=/usr/bin/gfortran F90=/usr/bin/gfortran FC=/usr/bin/gfortran FPATH=/usr/share/Modules/init/ksh-functions HISTCONTROL=ignoredups HISTSIZE=1000 HOME=/home/user HOSTNAME=me INVOCATION_ID=20e51c0c8a3b43e5a81235ce7f17e9e8 JOURNAL_STREAM=9:979914 KDEDIRS=/usr LANG=en_US.UTF-8 LESSOPEN=||/usr/bin/lesspipe.sh %s LOADEDMODULES= LOGNAME=user LS_COLORS=rs=0:di=01;34:ln=01;36:mh=00:pi=40;33:so=01;35:do=01;35:bd=40;33;01:cd=40;33;01:or=40;31;01:mi=01;05;37;41:su=37;41:sg=30;43:ca=30;41:tw=30;42:ow=34;42:st=37;44:ex=01;32:*.tar=01;31:*.tgz=01;31:*.arc=01;31:*.arj=01;31:*.taz=01;31:*.lha=01;31:*.lz4=01;31:*.lzh=01;31:*.lzma=01;31:*.tlz=01;31:*.txz=01;31:*.tzo=01;31:*.t7z=01;31:*.zip=01;31:*.z=01;31:*.dz=01;31:*.gz=01;31:*.lrz=01;31:*.lz=01;31:*.lzo=01;31:*.xz=01;31:*.zst=01;31:*.tzst=01;31:*.bz2=01;31:*.bz=01;31:*.tbz=01;31:*.tbz2=01;31:*.tz=01;31:*.deb=01;31:*.rpm=01;31:*.jar=01;31:*.war=01;31:*.ear=01;31:*.sar=01;31:*.rar=01;31:*.alz=01;31:*.ace=01;31:*.zoo=01;31:*.cpio=01;31:*.7z=01;31:*.rz=01;31:*.cab=01;31:*.wim=01;31:*.swm=01;31:*.dwm=01;31:*.esd=01;31:*.jpg=01;35:*.jpeg=01;35:*.mjpg=01;35:*.mjpeg=01;35:*.gif=01;35:*.bmp=01;35:*.pbm=01;35:*.pgm=01;35:*.ppm=01;35:*.tga=01;35:*.xbm=01;35:*.xpm=01;35:*.tif=01;35:*.tiff=01;35:*.png=01;35:*.svg=01;35:*.svgz=01;35:*.mng=01;35:*.pcx=01;35:*.mov=01;35:*.mpg=01;35:*.mpeg=01;35:*.m2v=01;35:*.mkv=01;35:*.webm=01;35:*.ogm=01;35:*.mp4=01;35:*.m4v=01;35:*.mp4v=01;35:*.vob=01;35:*.qt=01;35:*.nuv=01;35:*.wmv=01;35:*.asf=01;35:*.rm=01;35:*.rmvb=01;35:*.flc=01;35:*.avi=01;35:*.fli=01;35:*.flv=01;35:*.gl=01;35:*.dl=01;35:*.xcf=01;35:*.xwd=01;35:*.yuv=01;35:*.cgm=01;35:*.emf=01;35:*.ogv=01;35:*.ogx=01;35:*.aac=01;36:*.au=01;36:*.flac=01;36:*.m4a=01;36:*.mid=01;36:*.midi=01;36:*.mka=01;36:*.mp3=01;36:*.mpc=01;36:*.ogg=01;36:*.ra=01;36:*.wav=01;36:*.oga=01;36:*.opus=01;36:*.spx=01;36:*.xspf=01;36: MAIL=/var/spool/mail/user MODULEPATH=/etc/scl/modulefiles:/etc/scl/modulefiles:/usr/share/Modules/modulefiles:/etc/modulefiles:/usr/share/modulefiles MODULEPATH_modshare=/usr/share/modulefiles:1:/etc/modulefiles:1:/usr/share/Modules/modulefiles:1 MODULESHOME=/usr/share/Modules MODULES_CMD=/usr/share/Modules/libexec/modulecmd.tcl MODULES_RUN_QUARANTINE=LD_LIBRARY_PATH PATH=/usr/share/Modules/bin:/usr/local/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/home/user/dev/spack/bin:/home/user/dev/tlaplus/org.lamport.tla.toolbox.product.product/target/products/org.lamport.tla.toolbox.product.product/linux/gtk/x86_64/toolbox:/home/user/dev/spack/opt/spack/linux-fedora29-x86_64/gcc-8.2.1/gmsh-4.0.0-nlwykecq46dn3nnnexzxuvlny3zp2o6q/bin PS1=$HOSTNAME@$USER [$PWD]» PWD=/home/user/dev/universal-ctags SHELL=/usr/local/bin/ksh SHLVL=4 TERM=xterm-256color TERMINFO=/usr/share/terminfo USER=user VISUAL=nvim WINDOWID=67108874 WINDOWPATH=1 XAUTHORITY=/home/user/.Xauthority XDG_DATA_DIRS=/home/user/.local/share/flatpak/exports/share:/var/lib/flatpak/exports/share:/usr/local/share:/usr/share XDG_RUNTIME_DIR=/run/user/1000 XDG_SEAT=seat0 XDG_SESSION_ID=5 XDG_VTNR=1 XORG_RUN_AS_USER_OK=1 A__z=F*COMP_KEY=F*COMP_POINT=F*COMP_TYPE="*SHLVL

Something is really broken with your toolchain. Please attach the output of this command: $ gcc -v -g -Wall -o zzz regcomp.c It should log the GCC and link editor invocations. Please also check that # rpm -Va does not report any corrupt files.

This bug is really just weird. The behaviour your are seeing we would not expect, nor can we reproduce it. I would like you to note that the digest for: * /bin/bash, * /usr/bin/which, indicate alterations, which could mean your system is corrupted in some way. This is very suspicious e.g. rootkit level suspicious. I would suggest that you need to fix this system, test on another system, or reach out to the Fedora user help community. I'm closing this as CLOSED/NOTABUG for now.
