Follow-up Comment #5, bug #49532 (project octave):
This is becoming very strange. I have physical access to the Mac computer
today. When I try to run the test code directly, it gives the old error:
parcellfun: 0/2 jobs donepanic: Segmentation fault: 11 -- stopping myself...
panic: Segmentation fault: 11 -- stopping myself...
warning: parcellfun: premature exit due to closed pipe
warning: called from
parcellfun at line 347 column 11
pararrayfun at line 85 column 26
testing at line 90 column 1
warning: broken pipe
warning: broken pipe
with both gui and no gui
If I access the Mac remotely from my Linux machine, and run octave testing.m,
again I get:
parcellfun: 0/2 jobs donepanic: Segmentation fault: 11 -- stopping myself...
panic: Segmentation fault: 11 -- stopping myself...
warning: parcellfun: premature exit due to closed pipe
warning: called from
parcellfun at line 347 column 11
pararrayfun at line 85 column 26
testing at line 90 column 1
warning: broken pipe
warning: broken pipe
If I, additionally, logout from the Mac and login via ssh from my Linux
machine, and run octave testing.m,
Nov 8 08:20:53 octave[1055] <Error>: Set a breakpoint at CGSLogError to
catch errors as they are logged.
Nov 8 08:20:53 octave[1055] <Error>: This user is not allowed access to the
window system right now.
octave: no graphical display found
octave: disabling GUI features
Nov 8 08:20:53 octave-cli-4.2.0-rc2[1055] <Error>: Set a breakpoint at
CGSLogError to catch errors as they are logged.
Nov 8 08:20:53 octave-cli-4.2.0-rc2[1055] <Error>: This user is not allowed

parcellfun: 2/2 jobs done
So now it complains when starting octave, but the code runs fine. I am
clueless.
About BLAS, I did otools -L /usr/lib/libblas.dylib this is what I get:
/usr/lib/libblas.dylib:
/System/Library/Frameworks/Accelerate.framework/Versions/A/Frameworks/vecLib.framework/Versions/A/libBLAS.dylib
(compatibility version 1.0.0, current version 1.0.0)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version
1225.0.0)
I don't know how to check the stack on octave.
Does this help?
