BUG REPORT: Cygwin, g++, -O2, static member function, std::string

[Brad Bell]

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.
