This looks kind of like you're throwing an exception that isn't being
caught for some reason. We've had problems like this, and have usually
tracked it down to problems throwing exceptions across library
boundaries and/or not linking using g++. Are you linking everything
C++ish using g++? All C++ libraries and programs (or libraries and
program containing any C++) should be linked using g++. This can also
happen if you simply don't have a catch block that catches the type of
exception being thrown. That will cause your program to abort as well.
Cheers,
Lyle

Hi folks!
I have a big application and sometimes (not every build)
I get the following crash in the dynamically loaded shared object):
#0 0xdd8cefb7 in _lwp_kill () from /usr/lib/libc.so.1
#1 0xdd80a3ad in thr_kill () from /usr/lib/libthread.so.1
#2 0xdd8e50fd in raise () from /usr/lib/libc.so.1
#3 0xdd8cff5e in abort () from /usr/lib/libc.so.1
#4 0xdd9ec4bc in _ZN10__cxxabiv111__terminateEPFvvE () from
/usr/ADCAgent/libstdc++.so.5
#5 0xdd9ec3a3 in __gxx_personality_v0 () from
/usr/ADCAgent/libstdc++.so.5
#6 0xdd963d21 in _Unwind_GetTextRelBase () from
/usr/ADCAgent/libgcc_s.so.1
#7 0xdd963e52 in _Unwind_RaiseException () from
/usr/ADCAgent/libgcc_s.so.1
#8 0xdd9ec640 in __cxa_throw () from /usr/ADCAgent/libstdc++.so.5
#9 0xdb526552 in
...
...
It happens with gcc 3.2 in Solaris 8 Intel only (not in sparc) and with
optimization (-O2, -O3).
Unfortunately I am unable to reproduce this bug in a small test case
that's why
I can't show the source code here.
Could anybody suggest the way of how to catch the bug?
Or at least tell me please what the purpose of __gxx_personality_v0
function is?
I didn't find it in gcc source.
Any help will be greatly appreciated!
