This package is failing to build on ppc64el, but built successfully

https://buildd.debian.org/status/logs.php?pkg=graphicsmagick&arch=ppc64el
it regressed with 1.3.24+hg20160808-1, and the version currently in
sid is still failing. It looks like this is preventing migration to testing.
This is known and working with upstream to find the root cause.
A backtrace from a core dump is needed.
The list of toolchain package versions in the build logs suggests that
the regression might be due to the switch to GCC 6.
Definitely not. A code change in GraphicsMagick triggers it. I could
tighten it down, but don't know the exact cause yet.
There were no functions added or removed between 1.3.24 and 1.3.25 and
not interfaces were changed. If 1.3.24 still builds on the build
machine, then it is possible to test by replacing individual source
files in 1.3.25 with files from 1.3.24 and seeing when the problem
goes away. Since all tests are failing, the problematic code would
need to be used in initialization, or somehow always encountered.
Perhaps magick/utility.c would be a good starting point.
