I was trying to track down a threading problem with a sample class,

in my (brief) testing.

Any hints on what I might be doing wrong?

This error comes from the garbage collector. It means that the GC is trying to suspend the application's threads so that it can, but the win32 SuspendThread call is failing. You can look at this code in boehm-gc/win32-threads.c. I havn't heard of this error occuring before. Perhaps something is going wrong when registering the threads with the GC. A win32 expert, or investigation with gdb (check that the argument being passed to SuspendThread looks valid) may be able to tell you more.
