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 cannot be represented in type 'int' pmfileio.c:664:26: runtime error: left shift of 128 by 24 places cannot be represented in type 'int' pmfileio.c:664:26: runtime error: left shift of 128 by 24 places cannot be represented in type 'int' pmfileio.c:664:26: runtime error: left shift of 128 by 24 places cannot be represented in type 'int' 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.
