[Octave-bug-tracker] [bug #63931] Binary fwrite writes incorrect data to file

[John W. Eaton]

Follow-up Comment #12, bug #63931 (project octave):

I tried compiling with -Os with both clang (14.0.6) and gcc (12.2.0) on a
Debian system and I can't reproduce the problem with the t1.m script.  CLI vs.
GUI doesn't change anything for me.  I've also compiled with the default
configure options (-g -O2) on the same system with the same results.

Or at least I think the t1 script is not showing a problem.  Here is what I
see:


>> t1
val = 127
cw = 1
cr1 = 1
x = 127
y = 127
val = 128
cw = 1
cr1 = 1
x = 128
y = 128
val = 129
cw = 1
cr1 = 1
x = 129
y = 129


Is that the correct output?  Could you make the test script use assert or
error or something to clearly indicate what is an error instead of having to
compare output values visually?
