No, we do not have enough information to reproduce this issue, and the cause is not clear.

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. |
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]ยป 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
