please attach a backtrace from gdb.

gdb output is meaningless, I better attach strace

you're using gcc-4 ... please track down the bug on your system and get back to us

[Comment 5 Jeremy Huddleston (RETIRED) 2005-02-15 01:28:47 UTC]

or better yet, file the bug here: http://gcc.gnu.org/bugzilla/
