Closed fila43 closed 4 years ago

fila43 commented 4 years ago

I am trying build and test 0.7.0 on arm(Fedora 32) and tests fail with:

./ck_hclh 5 1
Creating threads (mutual exclusion)...done
Waiting for threads to finish correctness regression...make[2]: *** [Makefile:13: check] Segmentation fault (core dumped)

I am attaching full log: https://fjanus.fedorapeople.org/build.log

Hi, I can't seem to reproduce it. How many cores does your machine have ? And which gcc version is this ?

Thanks !

fila43 commented 4 years ago

Hi, thanks for fast response, in both cases it fails with 5 CPU and gcc version is: gcc aarch64 10.0.1-0.7.fc32

fila43 commented 4 years ago

It looks like it only occurs with 5 cores, 8 cores with the same software configuration succeeds

@fila43 is it better now ?

fila43 commented 4 years ago

@cognet now test ck_hclh looks fine, but other tests fail with make[2]: *** [Makefile:10: check] Segmentation fault (core dumped) here I have log: https://fjanus.fedorapeople.org/build-i686.log

Sorry this slipped through the cracks @fila43! Thank you for running these tests. We'll investigate more on our side.

Would it be possible to get core dumps? We are unable to recreate on our side. Let's track this on a separate issue though. I see it's impacting both ck_hp_stack and ck_stack. Confirming your logs, this is impacting x86 only?
