Hi Fred,

Tests to explicitly check cleanup handler execution were missing
from the test suite, which would explain why the problem hasn't been
noticed already. I've just written three more tests for this which
pass under the SEH implementation. Could you grab these from the CVS
repository and run them with your mingw build. They are called
cleanup*.c in the tests directory.

I'd like to retain the C++ destructor approach and fix whatever is
causing the problem you see. I'll forward your email to the list for
comment though.

Thanks again.

Ross
