           Summary: throw catchpoint doesn't catch rethrows
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: normal
          Priority: P2
         Component: c++
        AssignedTo: unassigned@sourceware.org
        ReportedBy: matz@suse.de


# cat bla.cc
int f (int i)
{
  try {
      if (i)
        throw;
  } catch (...) {
  }
  return i+1;
}

int main ()
{
  f(1);
  return 0;
}

# g++ bla.cc
# gdb ./a.out
(gdb) catch throw
catch throw
Function "__cxa_throw" not defined.
Catchpoint 1 (throw)
(gdb) b __cxa_rethrow
Breakpoint 1 at 0x4005a0

Perhaps it would be nice if 'catch throw' would also catch __cxa_rethrow.
As that might lead to too much noise in normal rethrow behaviour, perhaps
a new catchpoint type would be better.  One of our users ran into this and
was surprised that 'catch throw' didn't trigger on this one, and instead
it went down into the SIBABRT.

I have an implementation of "catch rethrow".
I'm still trying to decide if this is better than
just having "catch throw" catch them all.
