[Pkg-phototools-devel] Bug#1007234: Test suite fails on all but amd64 arches

[Bryan Henderson]

I haven't heard of this before.

I'm sure this is easy to diagnose for someone who can reproduce it.  I can't,
since I don't have access to a system other than AMD64.

I can tell from reading the code that what is happening is there is a
a negative number somewhere that there shouldn't be.  My best guess is that
the 2's complement arithmetic hack for interpreting the run-length-encoding
in the function 'readPackBitsRow16' in converter/other/pnmtopalm/palmtopnm.c
isn't doing what it's expected to do.  In particular, the line

  int const signedIncount = (signed char)incountByte

might be declaring a positive number, whereas it's supposed to be negative
(which means -signedIncount below is negative whereas it is expected to be
positive).
