[php-src] Issue #8185: pear install: error in malloc_consolidate

Issue: https://github.com/php/php-src/issues/8185 Comment Author: mokraemer this is strange - it even happens with my latest backport of php 8.1.5: https://ftp-stud.hs-esslingen.de/pub/Mirrors/Mageia/distrib/8/x86_64/media/core/backports_testing/ where php-8.0.18 installs without problems. Do you have a negative return code of pear-install? I'm not sure why this fails during destruction, but at least the write operation on the filedescriptor fails (since it was already closed). I'm not sure if this is "real" crash reason. What version of glibc are you using? I didn't see a problem during regular php runs - and php test cases run w/o problem. I've just checked glibc, but I don't see when fastbins are used and when normal bin used during malloc. And this test is only active on "fastbins".
