wierd ctest behaviour with tblis on mac

[janbrandejs]

When a clean build is done on Mac with gcc-14 and -DENABLE_TBLIS=1

the first call to ctest fails
Start 1: test++
1/2 Test #1: test++ ...........................Subprocess aborted***Exception: 1.18 sec
Start 2: demo
2/2 Test #2: demo ............................. Passed 0.47 sec

50% tests passed, 1 tests failed out of 2

log doesn't tell much:
LastTest.log

after this, if I run
./demo
./test++
ctest
again, suddenly everything works

Does just running test++ after a clean build encounter an exception?

[janbrandejs]

if i run
./test++
it works and the subsequent run of ctest works too.

It's only when ctest is ran first when the exception appears

I didn’t see that behavior with gcc-15 so I’m not sure how to help debug.

[janbrandejs]

Ok now I tried again the whole process with clean build and ctest worked. So I'm also unable to reproduce it anymore. I don't know what was happening there, but it's probably not a big deal.

10 minutes after closing this it's resurfaced again
Start 1: test++
1/5 Test #1: test++ ...........................Subprocess aborted***Exception: 0.03 sec

after installing on mac with cmake and gcc-14 (and tblis enabled)
this doesn't happen every time, but about every third run of ctest
