hm, I did not set any threading related options in configure, so I guess threading was not disabled.
I compiled it again with the following configure options,
--enable-debug --enable-memchecker --enable-mem-debug --disable-ft-thread --disable-progress-threads --disable-mpi-threads
and the behavior did change, although it still does not work completely. I will investigate further.
Thanks so far,
