Package: gdb
Version: 7.3-1+b1
Severity: important
Dear Maintainer,
* What led up to the situation?
Run gdb on SyncEvolution (compiled from source in my case).
Set a breakpoint in SyncEvo::Exception::handle().
Run so that an exception is thrown.
* What exactly did you do (or not do) that was effective (or
ineffective)?
Reading symbols from /home/pohly/work/syncevolution/src/syncevolution...done.

Create a core file of GDB? (y or n) n
I made that core file available here:
http://estamos.de/download/tmp/core-gdb-7.3-20111121.gz
Note that SyncEvo::Exception::handle() is an overloaded function
in a C++ program. I would have expected more than one breakpoint
to be set. I think that previous versions of gdb did that.
SyncEvo::Exception::handle() is called inside catch() blocks, *however*
further debugging shows that it wasn't invoked in the catch block of
this particular exception. But not setting the breakpoint avoids
the problem.
SyncEvolution was compiled with -g and no optimization. I also
tried with clang 2.9, same result.
