Hi, this bug happens on ppc64el and several other with the same error. I compared the .pam files generated on ppc64el and amd64 (whose test passed) and they have the same md5sum. The png being from the source, it actually looks like "compare" is giving a different output on ppc64el .
Digging deeper, it seems imagemagick is victim of https://gcc.gnu.org/bugzilla/show_bug.cgi?id=87036 , because I recompiled it with -ffp-contract=off and "compare" outputs a "0 (0, 0)". Not sure if imagemagick should use that flag, but for the time being wouldn't it possible to use a different metric for compare ? F.
