@nougad if you rebuild uwsgi against php 7.4 is the issue still present?
Comment by Pierre Schmitz (Pierre) - Sunday, 01 December 2019, 11:53 GMT
Sorry, this package was missing from the todo list. I have pushed version 2.0.18-5 to the repos. Does this fix your problem?
Comment by Florian (nougad) - Sunday, 01 December 2019, 12:54 GMT
I updated to 2.0.18-5 but I still get segfaults:

Comment by Florian (nougad) - Sunday, 01 December 2019, 12:59 GMT
maybe related upstream issue? https://github.com/unbit/uwsgi/issues/2096

For me it does not make a change if I enable/disable opcache (of course the stacktrace is different) but both segfault.

segfault with opcache =1 (above was the =0 version)

I fear this is probably an upstream issue then. Uwsgi only tests against PHP 7.2.

There is a upstream fix available: https://github.com/unbit/uwsgi/commit/c4a2ad579a2fe5d357f2d6486c1afe84ef18a029

Try rel -6.
Comment by Florian (nougad) - Thursday, 12 December 2019, 08:01 GMT
-6 works for me. Thank you!
Comment by Christoph (cobzcs) - Thursday, 12 December 2019, 08:35 GMT
It's also working for me. Thanks.
