             Bug #: 14062
           Summary: Exceptions in callbacks posted by gdb.post_event are
                    silently ignored.
           Product: gdb
           Version: 7.4
            Status: NEW
          Severity: normal
          Priority: P2
         Component: python
        AssignedTo: unassigned@sourceware.org
        ReportedBy: gareth@blacksphere.co.nz
    Classification: Unclassified


This is the simplest example to reproduce this problem:

(gdb) python invalid()
Traceback (most recent call last):
  File "<string>", line 1, in <module>
NameError: name 'invalid' is not defined
Error while executing Python code.
(gdb) python gdb.post_event(lambda : invalid())
(gdb)

Note that the exception in the lambda function is never reported.

This is observed on GDB 7.4.1 (target arm-none-eabi) with Python 2.6.6 and
Linux 2.6.35-32 (Ubuntu 10.10).
