FAIL: test_invert
=================

Segmentation fault (core dumped) 
FAIL test_invert (exit status: 139)

Probably random tests errors are due to a minor quirk in OS random facilities, but segfault in test_inverse is a worry.

I can offer access to an OpenBSD host if aonyone wants to have a go in fixing this.

I tried to see if I can reproduce on Debian GNU/Linux with Clang 7 but no dice:

CC=clang ./configure --enable-debug && make -j4 check 

passes. I tried running the same in an OpenBSD box but I can’t even do make check

libtool:   error: require no space between '-L' and '-Wl,-rpath,'
*** Error 1 in target 'test_multiplication'
libtool:   error: require no space between '-L' and '-Wl,-rpath,'
*** Error 1 in target 'test_elimination'
libtool:   error: require no space between '-L' and '-Wl,-rpath,'
*** Error 1 in target 'test_trsm'
libtool:   error: require no space between '-L' and '-Wl,-rpath,'

[Dmitrii Pasechnik]

Are you sure you’re not using BSD make (I naturally used GNU make)

[Dmitrii Pasechnik]

$ ./config.status --config
'--prefix=/home/dima' 'CC=clang' 'CFLAGS=-I/usr/local/include ' 'LDFLAGS=-L/usr/local/lib ' 'CPPFLAGS=-I/usr/local/include 

and this is how I configured. Perhaps you cannot skip --prefix ?

[Martin Albrecht]

That did indeed do the trick, can you check again, I might have fixed the sigsegv.

[Dmitrii Pasechnik]

Yep, the sigsegv is gone for me too, only the test_random still fails.

[Martin Albrecht]

I can’t reproduce those on OpenBSD openbsd6.localdomain 6.6 GENERIC.MP#372 amd64

[Dmitrii Pasechnik]

maybe it’s because I’m running openbsd 6.6 on a VM hosted on openbsd (https://openbsd.amsterdam/), I get this error.

OpenBSD sagemath.openbsd.amsterdam 6.6 GENERIC#7 amd64

What’s the status?
