Subject: gdb aborts after setting "throw" catchpoint
Content-Type: text/plain; charset=ISO-8859-1; format=flowed
Content-Transfer-Encoding: 7bit

Hi all,

Compiling the following with the cygwin g++-4.5.3:

int global;
int main() {
     if (global)
         throw global;
     return 0;
}

Crashes gdb if a catchpoint is set:

GNU gdb (GDB) 7.6.50.20130408-cvs (cygwin-special)
... snip...
Reading symbols from /home/Ryan/experiments/a.exe...done.
(gdb) catch throw
Catchpoint 1 (throw)
(gdb) r
Starting program: /home/Ryan/experiments/a.exe
[New Thread 10024.0x1480]
[New Thread 10024.0x1758]
warning: SuspendThread failed. (winerr 6)
[Inferior 1 (process 10024) exited normally]
(gdb)
Debugger aborted (core dumped)

Has anybody seen this problem before? Meanwhile, setting a breakpoint on 
__cxa_throw works just fine, so at least there's a workaround.

Thoughts?
Ryan
