The issue is a failing test in test/run_tests.bash:
head fish1.png > ${tmpdir}/fake.png
"$pdiff" --verbose fish1.png ${tmpdir}/fake.png 2>&1 | grep -q 'Failed to
load'
rm -f ${tmpdir}/fake.png
Here it's making sure that we are able to detect a corrupt .png file,
and to throw an error. The actual image load is being done by
libfreeimage. For whatever reason, on amd64 (and other non-breaking
platforms) FreeImage_Load() returns NULL when given this corrupt file,
which is what the test expects. But on the failing platforms it throws a
c++ exception instead. The test doesn't catch this exception and
crashes, causing this FTBFS.
I tried to catch this exception nicely with the attached patch, but for
some reason it doesn't work. Since this problem isn't in the main part
of the library, we should simply disable this particular test to resolve
the FTBFS and this RC bug.
If I don't hear back in a few days, I'm going to do an NMU with this
patch.
Thanks.
