The object containing the throw and the catch



gcc version 4.7.2 (GCC) 

Target: sparc-sun-solaris2.10

Configured with: /proj/vobadm100/svn/gcc_4.7.2/configure \

  --prefix /vobs/cello/cade_A_tools_gcc \

  --with-gnu-as --with-as=/vobs/cello/cade_A_tools_utils/binutils/bin/as \

  --with-gnu-ld --with-ld=/vobs/cello/cade_A_tools_utils/binutils/bin/ld \

  --with-mpc=/vobs/cello/cade_A_tools_utils/mpc \

  --with-isl=/vobs/cello/cade_A_tools_utils/isl



The command line is:



$ ./CoreTest

Segmentation Fault



It runs a small test case reproducing the problem.

I attach the two preprocessed sources: Core.ii and CoreTest.ii.

Here is the stack trace produced by gdb:

I put the main function itno a separate file, but you want only one

attachment...

The source is trivial anyway:



$ cat CoreTest.cc

#include "Core.h"



int main() {

ThrowException();

return 1;

}

OK. Good to know. I configured with GNU, hence there is something in the tool

chain which results in the problem.

Under the debugger, I get the segfault stepping into the call to 'get_global()'

in libstdc++-v3/libsupc++/eh_globals.cc:63.

I can find only one declaration of this get_global, and it is earlier in

eh_globals.cc:50.

Looking at the decorations in the symbols:



gcc> nm ./sparc-sun-solaris2.10/libstdc++-v3/libsupc++/eh_globals.o

 U _GLOBAL_OFFSET_TABLE_

 d _ZL16__gthread_active

 b _ZZN12_GLOBAL__N_110get_globalEvE6global

 T __cxa_get_globals

 T __cxa_get_globals_fast

 W __sparc_get_pc_thunk.l7

 U __tls_get_addr



I wonder if there is a mismatch between the offering and the request?

What symbols do you have, in the Sun configuration?

Note that I was handed another gcc, compiled independently for the same

platform, and which displays the same issue.

Sorry: the other compiler works once I set LD_LIBRARY_PATH to use its

libstdc++.so.6 and libgcc_s.so.1

I can acknowledge that installing binutils 2.23.2 solved my problem with gcc
