While using ImageMagick, I got the following error message

troutmask:kargl[209] display case3b-wth-longrange.jpg 
Assertion failed: (mapelm.free == false), function arena_dalloc, file /usr/src/lib/libc/stdlib/malloc.c, line 2440.
Abort (core dumped)

Unfortunately, the backtrace doesn't give too much info

On this system, I have /etc/malloc symlinked to aj.
libc and kernel are from 7 Feb 07 sources.
