Math failures are old and related to misused FPU control https://bugs.php.net/bug.php?id=79595

cmb69 · 2022-08-17T15:11:16Z

Hmm, are these tests segfaulting?

andypost · 2022-08-17T15:52:09Z

No, just wrong results

andypost · 2022-08-19T11:01:44Z

Just got results from 8.1.10RC1 and there's 3 more tests failed on ppc64le arch

Throw in multiple destroyed fibers after shutdown [Zend/tests/fibers/throw-in-multiple-destroyed-fibers-after-shutdown.phpt]

not sure it's related but diffs are https://gitlab.alpinelinux.org/alpine/aports/-/merge_requests/37880#note_256882

I'm fairly certain this is the same root cause as in GH-10398 and is probably fixed by GH-10407.

cmb69 · 2023-01-28T12:43:02Z

I'm fairly certain this is the same root cause as in GH-10398 and is probably fixed by GH-10407.

Can you please check this, @andypost?

andypost · 2023-02-03T20:36:40Z

I added PR as patch and in 1h tests will show https://gitlab.alpinelinux.org/alpine/aports/-/jobs/965476

Also I enabled all previously failed x86 tests for fibers

andypost · 2023-02-03T20:40:49Z

@cmb69 please suggest a way to report https://gitlab.alpinelinux.org/alpine/aports/-/issues/14381 maybe after asm upgrades libc will has less effect

Thank you! (For the readers who only check this thread, it is fixed indeed: #10407 (comment))

https://gitlab.alpinelinux.org/alpine/aports/-/issues/14381

I looked at the metaphone case and the slowdown was because of a lot of libc calls. I optimized it here: #10501 by removing redundant libc calls. I could also take a look at the other string functions in the near future.

andypost · 2023-02-05T17:09:30Z

Yes, it fixed all this x86 tests, probably ppc 3 tests could use separate issue

andypost · 2023-02-05T17:11:36Z

The failed tests are #10407 (comment)
