See also problem report lib/1005, where I reported a problem with quad
multiplication. Unfortunately the comments preceding the program
example is slightly misleading as they were meant for another version
of the test program. It also turns out that this is an architecure
dependent or maybe an endian-problem, as the test program runs fine on
an hp300-series machine, but produces the wrong result on my i486.
The results from the program are:
(quad) x=80000000, y=2, z=ffffffff00000000
(little) x=0:80000000, y=0:2, z=ffffffff:0
(quad) x=80000000, y=2, z=100000000
(big) x=0:80000000, y=0:2, z=1:0
Maybe this problem and your problem are related?
