thread lockup when comiling with optimizations.

Patrick Stinson

I've added an extra thread to my application read from an alsa midi device,
and when I compile with any optimizations (gcc -O3 or gcc -O2) the
application "freezes" (meaning I don't know what code is still executing)
after the last of my threads (I have three, including the main thread).

This does not happen w/o optimizations.

Cheers

Your issue cannot be resolved in terms of the standard C++ language. It
doesn't define threads, and optimisations are compiler-specific. Ask in
a newsgroup dedicated to your OS and/or your compiler.

You're in the wrong place. Comp.lang.c++ deals with Standard C++, which
has no concept of threading. Try in a newsgroup dedicated to your compiler
vendor and/or O/S platform.
