I'm suffering stack overflow in a program that uses both multiple
processes and multiple threads. Can anyone help me interpret the
following -xc output? In particular, which ... reports relate to
the stack overflow? (I've added a newline following each '' to
increase readability.) I

You should not need the latter two step, if you use the --with-gcc

to configure, as the building guide

The formal semantics in the notes doesn't have a good way to express

Hi again.
Thanks for the feedback.
The only way I know to make all this work is to use a straightforward
Cygwin environment for building (with absolutely no mingw
stuff in your
path) and use --with-gcc in your configure line. Other
things may work,
but you're on your own.
