C-code to reproduce the bug
Still not fixed in gcc 4.0. Upstream PR already exists: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=10865 |
Description of problem: gcc3's "-pthread" option does not set the -D_REENTRANT compilation flag. the link flag -lpthread is correctly set. Version-Release number of selected component (if applicable): gcc3 -v Reading specs from /usr/lib/gcc-lib/ia64-redhat-linux/3.0.4/specs Configured with: ../configure --prefix=/usr --mandir=/usr/share/man --infodir=/usr/share/info --enable-shared --enable-threads=posix --disable-checking --host=ia64-redhat-linux --with-system-zlib Thread model: posix gcc version 3.0.4 (Red Hat Linux 7.2 3.0.4-1) How reproducible: Steps to Reproduce: 1. get the attached program pthbug.c 2. compile it with gcc3 -v -pthread -Wall -Wstrict-prototypes pthbug.c 3. note that -D_REENTRANT is not defined Actual results: gcc3 -v -pthread -Wall -Wstrict-prototypes pthbug.c Reading specs from /usr/lib/gcc-lib/ia64-redhat-linux/3.0.4/specs Configured with: ../configure --prefix=/usr --mandir=/usr/share/man --infodir=/usr/share/info --enable-shared --enable-threads=posix --disable-checking --host=ia64-redhat-linux --with-system-zlib Thread model: posix gcc version 3.0.4 (Red Hat Linux 7.2 3.0.4-1) /usr/lib/gcc-lib/ia64-redhat-linux/3.0.4/cc1 -lang-c -v -D__GNUC__=3 -D__GNUC_MINOR__=0 -D__GNUC_PATCHLEVEL__=4 -D__ia64 -D__ia64__ -D__linux -D__linux__ -D_LONGLONG -Dlinux -Dunix -D__LP64__ -D__ELF__ -D__ia64 -D__ia64__ -D__linux -D__linux__ -D_LONGLONG -D__linux__ -D__unix__ -D__LP64__ -D__ELF__ -D__linux -D__unix -Asystem=linux -Acpu=ia64 -Amachine=ia64 -D__NO_INLINE__ -D__STDC_HOSTED__=1 -Wall -Wstrict-prototypes -D__LONG_MAX__=9223372036854775807L pthbug.c -quiet -dumpbase pthbug.c -Wall -Wstrict-prototypes -version -o /var/tmp/fxk/ccOy4gQr.s GNU CPP version 3.0.4 (Red Hat Linux 7.2 3.0.4-1) (cpplib) (IA-64) Linux GNU C version 3.0.4 (Red Hat Linux 7.2 3.0.4-1) (ia64-redhat-linux) compiled by GNU C version 3.0.4 (Red Hat Linux 7.2 3.0.4-1). ignoring nonexistent directory "/usr/ia64-redhat-linux/include" #include "..." search starts here: #include <...> search starts here: /usr/local/include /usr/lib/gcc-lib/ia64-redhat-linux/3.0.4/include /usr/include End of search list. pthbug.c:9:2: #error "_REENTRANT undefined" Expected results: gcc3 -v -pthread -Wall -Wstrict-prototypes pthbug.c Reading specs from /usr/lib/gcc-lib/ia64-redhat-linux/3.0.4/specs Configured with: ../configure --prefix=/usr --mandir=/usr/share/man --infodir=/usr/share/info --enable-shared --enable-threads=posix --disable-checking --host=ia64-redhat-linux --with-system-zlib Thread model: posix gcc version 3.0.4 (Red Hat Linux 7.2 3.0.4-1) /usr/lib/gcc-lib/ia64-redhat-linux/3.0.4/cc1 -lang-c -v -D__GNUC__=3 -D_REENTRANT -D__GNUC_MINOR__=0 -D__GNUC_PATCHLEVEL__=4 -D__ia64 -D__ia64__ -D__linux -D__linux__ -D_LONGLONG -Dlinux -Dunix -D__LP64__ -D__ELF__ -D__ia64 -D__ia64__ -D__linux -D__linux__ -D_LONGLONG -D__linux__ -D__unix__ -D__LP64__ -D__ELF__ -D__linux -D__unix -Asystem=linux -Acpu=ia64 -Amachine=ia64 -D__NO_INLINE__ -D__STDC_HOSTED__=1 -Wall -Wstrict-prototypes -D__LONG_MAX__=9223372036854775807L pthbug.c -quiet -dumpbase pthbug.c -Wall -Wstrict-prototypes -version -o /var/tmp/fxk/ccOy4gQr.s GNU CPP version 3.0.4 (Red Hat Linux 7.2 3.0.4-1) (cpplib) (IA-64) Linux GNU C version 3.0.4 (Red Hat Linux 7.2 3.0.4-1) (ia64-redhat-linux) compiled by GNU C version 3.0.4 (Red Hat Linux 7.2 3.0.4-1). ignoring nonexistent directory "/usr/ia64-redhat-linux/include" #include "..." search starts here: #include <...> search starts here: /usr/local/include /usr/lib/gcc-lib/ia64-redhat-linux/3.0.4/include /usr/include End of search list. Additional info: 1) The following distributions+compilers are not affected by this problem. - ia32 + RedHat 2.1AS + gcc-2.96 - ia64 + RedHat 2.1AS + gcc-2.96 - ia32 + RedHat 7.3 + gcc-2.96 - ia32 + RedHat 7.2 + gcc-2.96 - ia64 + RedHat 7.2 + gcc-2.96 2) An application core-dump occurs when a C++ library is unloaded (call _fini), because the libpthread destruction invokes application destructors that are not compiled to support multi-thread.
