I've been having a problem with ORBit from the gnome2 alpha. See
http://mail.gnome.org/archives/orbit-list/2002-January/msg00114.html for
a thread discussing it.
In brief, when I try and start an executable called server I get a core
dump.
If I run gdb against this dump I don't get any useful symbols.
Running strace would indicate that the program is either linking or has
just finished linking when it dies.
I've tried reinstalling glibc (2.2.5) - as I belive (from the offsets
shown by ldd) that the program is running /lib/ld-linux.so.2 when it
dies.
I tried to include debugging symbols by compiling with -g among my
CFLAGS.
Is there something else I should do to enable symbols?
I'm using gcc-3.0.3 and a pretty recent binutils (something from the
2.10.1 range).
I don't appear to get this problem with any other binaries.
Can anyone suggest anything that may help?
cheers
Loz
