There is a race condition in https://github.com/php/php-src/blob/ec277ce7fe1e7b7f98e270198826fc1432cdcb3d/ext/openssl/tests/gh13860.phpt: If the first
fread($fp, 2);(line 36) is executed afterfwrite($client, "xx");, the test hangs indefinitely in the loop: https://github.com/php/php-src/blob/ec277ce7fe1e7b7f98e270198826fc1432cdcb3d/ext/openssl/tests/gh13860.phpt#L39C1-L41C6I've observed this on Alpine with a ZTS + ASAN build, in #13925, but adding a sleep() before the first fread() will also reproduce the issue.
Moving the
phpt_wait()beforefwrite()fixes the hang by ensuring thatfread($fp, 2);executes beforefwrite(). However I'm not sure this is still testing the right thing (although the test fails if I revert 2aae14c).
