>Description:
I'm using the -finstrument-functions option to create
a simple profiling library. If the instrumented program
throws an exception, then __cyg_profile_func_exit doesn't
get called when the exception propagates up the call stack.

I don't know if it's supposed to be that way,
but I think it makes the option much less useful.
>How-To-Repeat:
g++ -ansi -Wall -c -o instrument1.o instrument1.cc
g++ -ansi -Wall -finstrument-functions -c -o instrument2.o instrument2.cc
g++ -o instrument instrument1.o instrument2.o
./instrument
