Thank you very much for the bugreport. Sent upstream: http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=19648
Please can you provide backtrace of problem? It is requested by upstream authors.
After the glibc appears I get the following baktrace (pstack pid). Anyway, the bug can be reproduced 100% of the times, so it is easy to get backtraces with the version released in Fedora 15: #0 0x004d2424 in __kernel_vsyscall () #1 0x41242c42 in __lll_lock_wait_private () from /lib/libc.so.6 #2 0x411d07f2 in _L_lock_10167 () from /lib/libc.so.6 #3 0x411ceb3c in malloc () from /lib/libc.so.6 #4 0x4102c3ae in _dl_map_object_deps () from /lib/ld-linux.so.2 #5 0x4103137b in dl_open_worker () from /lib/ld-linux.so.2 #6 0x4102d83f in _dl_catch_error () from /lib/ld-linux.so.2 #7 0x41031a56 in _dl_open () from /lib/ld-linux.so.2 #8 0x41271db2 in do_dlopen () from /lib/libc.so.6 #9 0x4102d83f in _dl_catch_error () from /lib/ld-linux.so.2 #10 0x41271edb in __libc_dlopen_mode () from /lib/libc.so.6 #11 0x41249538 in init () from /lib/libc.so.6 #12 0x4107e72e in pthread_once () from /lib/libpthread.so.0 #13 0x412497a5 in backtrace () from /lib/libc.so.6 #14 0x411c43b0 in __libc_message () from /lib/libc.so.6 #15 0x411cb2b5 in malloc_printerr () from /lib/libc.so.6 #16 0x411cb5c6 in malloc_consolidate.part.3 () from /lib/libc.so.6 #17 0x411cbd41 in _int_free () from /lib/libc.so.6 #18 0x4182be01 in RelinquishMagickMemory () from /usr/lib/libMagickCore.so.4 #19 0x418f516f in DestroyXResources () from /usr/lib/libMagickCore.so.4 #20 0x418f55a5 in XComponentTerminus () from /usr/lib/libMagickCore.so.4 #21 0x4182a0c2 in MagickCoreTerminus () from /usr/lib/libMagickCore.so.4 #22 0x080486ee in ??
