crash while testing imread.m

[Ben Abbott]

I encountered a new failure building today (its been about 2-3 weeks since my 
last build).

  scripts/image/imread.m .................................Assertion failed: 
(semaphore_info != (SemaphoreInfo *) NULL), function LockSemaphoreInfo, file 
magick/semaphore.c, line 525.

I'm unfamiliar with this part of the code. Does anyone have an idea of what may 
have changed?

My graphicsmagick is at version 1.3.10-1
