[Fnccheck-devel] functioncheck and stl

[Polly P. <ppo...@in...>]

Greetings,

I am using FunctionCheck 3.0.11 with gcc 2.95.2 on a Debian woody 
system, and I am getting a segfault in libfc. When my executable is 
relinked without libfc, it runs correctly.

Here is a snippet of my gdb 5.1 backtrace:

Program received signal SIGSEGV, Segmentation fault.
[Switching to Thread 1024 (runnable)]
0x4001fc46 in fc_com_enter () from /usr/local/lib/libfc.so.0
(gdb) bt

(__initialize_p=1,
     __priority=65535) at /usr/include/g++-3/stl_alloc.h:419

I compiled libfc with debugging enabled and set the appropriate 
environmental variable, but didn't seem to get any debugging output I 
could pass along.

This is a multithreaded process. Here are the environmental variables set:

FC_ALLOW_THREAD=1
FC_DEBUG=1
FC_HELP=1
LD_LIBRARY_PATH=/usr/local/lib

My libfc.so is in /usr/local/lib, and an ldd of my binary shows that it 
is properly linked. I doublechecked that my ccflags were set correctly. 
Fc_manager is in my path.

The 3.0.11 Release Notes indicate that it has a fix for C++ templates, 
and I haven't found any open bug reports that seem relevant.

Does anyone have any ideas about what I should do next? Any suggestions 
would be most welcome.

Thanks in advance,

Polly Powledge
