Very Embarrassed!!!

I went back to having openmp enabled:

./configure --enable-delegate-build --enable-shared --disable-static \
--with-modules --with-quantum-depth=16 --with-gslib --without-wmf \
--enable-libtool-verbose --disable-dependency-tracking \
--with-gs-font-dir=/usr/local/share/ghostscript/fonts/ --with-lqr

And ran

montage -label "test" -geometry +0+0 logo: logo_montage.gif


It actually finished in IM 6.5.2-4 Q16 Mac OSX Tiger.

I am puzzled why it did not seem to finish when I first installed this release. Perhaps I did not wait long enough.

But I am sure that it did not work in IM 6.5.2-3 Q16 Mac OSX Tiger. Perhaps it was some glitch, but I reinstalled and tested twice and it still failed to finish.

Again my apologies for the false alarm with IM 6.5.2-4.

Thanks for your help.

There appears to be a race condition with OpenMP under Mac OS X. We could only get montage to fail by putting it in a loop and after several hundred executions it would hang. We think the problem is fixed by changing the scheduling from dynamic to static. We'll do some additional testing tomorrow.
