commit c4901206cff33e5e1eae76684a9d8f416df29af5
Author: Charles Wilson <address@hidden>
Date:   Sat Jun 19 16:29:45 2010 -0400

    [cygwin] Fix segfault in C++ exception handling test
    
    * tests/exceptions.at (main.cpp:exceptions_in_module):
    Move dlclose outside catch block; otherwise __cxa_end_catch
    (part of the cygwin g++ ABI) accesses pointers to data inside
    unloaded DLL. This is a platform ABI-specific bug, but is
    likely common to many platforms' g++ and/or other C++
    compilers.
