I am going to discard the test-suite result in Debian package.
Something is not quite right on my side.

Compiling netpbm with gcc-10+ubsan gives odd results on my amd64:

== palm-roundtrip.test ==
pamdepth: promoting from black and white to grayscale
pnmcolormap: making histogram...
pnmcolormap: Scanning image 0
pnmcolormap: 20314 colors so far
pnmcolormap: 20314 colors found
pnmcolormap: choosing 256 colors...
pnmremap: 256 colors found in colormap

pmfileio.c:664:26: runtime error: left shift of 128 by 24 places

palm-roundtrip.test: FAILURE

I am going to /assume/ code is not tested on arch other than amd64, so
I think this is acceptable behavior.


Thanks for your help.
