other/10778: Exception handling seems to fail on a powerpc using GCC 3.2.3powerpc-eabi cross compiler

[mhessel@xs4all.nl]

When throwing an exception the (see attachment 'main.cpp') the call to the
constructor of the class that handles the exception is done well (see
attachment 'exception #1.gif').

After construction, the related 'catch' part should be called. Looking
into the generated assembly by the powerpc-eabi GCC v3.x, the exception
handling part does not seem to find the catch part. The exception seems to
fail after calling 'uw_frame_state_for' (see attachment 'exception
#1.gif'). The exception is aborted because the 'bne- 0x225f8
<uw_init_context_1+160>' is taken (the abort function is called).

Cheers,
Marwijn
