Last modified: 2007-11-30 17:10:41 EST
Description of problem: I get "Floating point exception" when I compile glibc-2.3.3_cvs-200404291129 with gcc 3.4.0, install it and run practically anything which uses threads. I do not use fedora, i downloaded cvs head using cvs and built it with the options in the fedora src rpm. compiling with linuxthreads works perfectly fine Version-Release number of selected component (if applicable): n/a How reproducible: 100% Steps to Reproduce: 1. install gcc 3.4.0 2. compile and install glibc cvs head as per above 3. try run say sendmail Actual results: Shutting down sendmail: [ OK ] Starting sendmail: /etc/init.d/sendmail: line 4: 22997 Floating point exception/usr/bin/newaliases >/dev/null 2>&1 /etc/init.d/sendmail: line 7: 22998 Floating point exceptionmakemap hash /etc/mail/$i </etc/mail/$i /etc/init.d/sendmail: line 7: 22999 Floating point exceptionmakemap hash /etc/mail/$i </etc/mail/$i /etc/init.d/sendmail: line 7: 23000 Floating point exceptionmakemap hash /etc/mail/$i </etc/mail/$i /etc/init.d/sendmail: line 7: 23001 Floating point exceptionmakemap hash /etc/mail/$i </etc/mail/$i [FAILED] if you run anything using thread support, it returns "Floating Point Exception" Expected results: it working? heh Additional info:
Well, if you roll your own, you are on your own debugging what's wrong as well, the report doesn't belong here, but on sources.redhat.com/bugzilla and need to include more relevant details, such as gdb session where it crashed with SIGFPE etc. It certainly works for me.
