Are you gonna backport this into 7.4.13? Previous Comments: ------------------------------------------------------------------------ [2020-11-18 15:02:54] nikic@php.net There is some chance that this issue is fixed by https://github.com/php/php-src/commit/99a8ec6e24d2788bb533ab5be8618a958adf24cf. At least this seems like a plausible cause, but it may also be unrelated. ------------------------------------------------------------------------ [2020-10-22 16:36:28] aa dot vasilenko at gmail dot com I've stumbled upon the same problem. Problem is reproducible only with php 7.4 (alternatively tried 7.3, it worked), using phpunit 9.1. In our case it's debian though. Works flawlessly without code coverage, segfaults with code coverage on (100% reproducible).
