[Bug 937380] [NEW] libmagick hangs when called from RMagick with Passenger 3

[Matthew M. Boedicker]

Public bug reported:

ruby processes using libmagick via the RMagick gem hang when running
under Passenger 3.0.11. The requests never return.

Installing debug libraries and looking at one of the stuck processes
with gdb gives this:

#0  futex_wait (val=0, addr=0x3858984)
    at ../../../src/libgomp/config/linux/x86/futex.h:44
#1  do_wait (val=0, addr=0x3858984) at ../../../src/libgomp/config/linux/wait.h:58
#2  gomp_team_barrier_wait_end (bar=0x3858980, state=0)
    at ../../../src/libgomp/config/linux/bar.c:109
#3  0x00007f876709b6ce in gomp_team_end () at ../../../src/libgomp/team.c:464
#4  0x00007f876840a919 in SetImageBackgroundColor (image=0x1d27600)
    at magick/image.c:2837
#5  SetImageBackgroundColor (image=0x1d27600) at magick/image.c:2792
#6  0x00007f876879749e in Image_initialize ()
   from /usr/lib/ruby/gems/1.8/gems/rmagick-2.13.1/lib/RMagick2.so

The problem does not occur when using the Ubuntu Passenger package, only
with more recent versions of Passenger.
