What distribution and what version of e2fsprogs is this user using?
I'm going to guess that he is using SuSE or some OpenSuSE derivitive,
and it's because SuSE bludgeoned in a pthreads mutex into the
internals of libcom_err. Since libext2fs can call libcom_err, it
follows that a program that links with libext2fs needs to also be
compiled and linked with -pthread.
It's for this reason I've resisted including SuSE's, because the race
they are concerned about is largely theoretical, and it causes
problems for people who want to link against libcom_err.
What I probably should do add in locking using sem_wait/sem_post,
which doesn't require any Posix pthread nonsense.
