I seem to have run across a bug using g++ with -O2 under Cygwin. It has 
to do with using static class member functions and standard string.

The bash shell script command
    ./bug.sh
creates three files, compiles, links, and runs the result. I have run 
this command on several Cygwin systems and gotten results similar to 
those in bug_cygwin.out; i.e., the assert
    assertion r != 0 failed
I have run the same command on several Linux systems and gotten results 
similar to those in bug_linux.out; i.e., no assertion.


Can you post the bug{1,2}.cpp files? I would guess that its not a bug, 
but rather you are relying on an undefined order of static 
initialization that happens to do what you want sometimes but not 
others. It's impossible to say for sure without seeing the source files, 
though.
