This is a reply to the message
 	http://cygwin.com/ml/cygwin/2007-10/msg00508.html
where the following request was made
 	Can you post the bug{1,2}.cpp files ? 
Note that the original bug report is at
 	http://cygwin.com/ml/cygwin/2007-10/msg00507.html

I am attaching the requested files as well as a neceesary include file. 
All these files are created by bug.sh when it is run.

I did not realize that it is hard to open *.sh files as text (when they 
are attached to a message). Sorry about that. I am including the bug.sh 
script below:

---------------------- cut here ------------------------------------------ 
#! /bin/bash # echo "BUG REPORT:  Cygwin, g++, -O2, static member 
function, std::string" echo "RUN COMMAND:  $0 $*" echo "RESULT: 
assertion \"r != 0\" failed" echo "SIDE EFFECTS: the files ./bug0.hpp, 
bug1.cpp, and bug2.cpp are created." # cat << EOF > bug0.hpp # include 
<string> class Element { public:
 	std::string   file;

 	static Element *root(void)
 	{	static Element r;
 		return &r;
 	}

}; 
EOF
cat << EOF >  bug1.cpp
# include "bug0.hpp"
extern void bug2(void);
int main(void)
{	std::string str("A");
 	char c = str[0];

 	Element *r = Element::root();
 	bug2();

 	return 0;
}
EOF
cat << EOF > bug2.cpp
# include <cassert>
# include "bug0.hpp"
void bug2(void)
{
 	Element *r = Element::root();
 	Element *s = Element::root();

 	assert( r != 0 );
}
EOF

echo "uname -a"
uname -a

g++ bug1.cpp bug2.cpp  -O1 -o bug
