First of all, thanks for the testing.
It would be nice if anyone else with macppc could do some similar
tests with poppler-0.82.0, so we can see wether this is a regression
or not.
I had a quick look on the diffs between poppler-0.82.0 and poppler.0.83.0,
and I didn't see anything obvious which could have introduced bugs
wrt endianess or colour handling in poppler; there are some changes
like from
if (foo.isNum())
bar = foo.getNum()
to
bar = foo.getNumWithDefaultValue(some_default)
in the color area, but they don't look as if they wouldn't have
also introduced problems on other architectures.
And for the memory consumption: not sure what could have caused
this *if* this is a regression in poppler-0.83.0.
Ciao,
