[Bug c++/11031] gdb terminates when trying to set breakpoint at C++ exception

["ppluzhnikov at google dot com" <sourceware-bugzilla at sourceware dot org>]

------- Additional Comments From ppluzhnikov at google dot com  2009-11-30 04:03 -------
Does not reproduce for me using gdb-7.0 (official release) built with "gcc.exe
(GCC) 4.4.0" from:
http://sourceforge.net/projects/mingw/files/GCC%20Version%204/gcc-core-4.4.0-mingw32-bin.tar.gz/download

Here is what I see:

$ cat t.cc
int main(int argc, char *argv[])
{
  if (argc > 1)
    throw 1;
  return 0;
}

$ g++ -g t.cc -o t

$ ~/gdb-7.0/build-mingw32/gdb/gdb ./t.exe
