Jeremy,

I was unable to reproduce the problem on Win2K using gcc 3.3.1, MinGW
runtime 3.0, MinGW W32API 2.3. My machine is an Athlon 550 MHz with
900 MB RAM. I tried the test case compiled with  

g++ -g -mthreads 

and with

g++ -g -mthreads -O2 

and ran it for 12 minutes each time. It was necessary to add #include
<windows.h> after #include <string>

Next time you report a problem, please provide at least as much
details as shown above. This helps us to help you.

I guess the gcc version your cygwin uses has not the MinGW patches, or
your MinGW runtime is too old. The fact that your test case doesn't
require an #include <windows.h> hints that you are not using the most
recent MinGW installation.

Earnie & Co.: what's the current policy wrt -mno-cygwin and this
mailing list?
