Description Marcus Comstedt 2022-12-04 11:28:02 UTC
If jit is enabled (which it is by default), PCRE crashes on a trivial regexp on big endian aarch64.

This is very unfortunate since portage uses "grep -P" in the image directory,
resulting in every package trying to install a file "/core"...

Reproducible: Always

Steps to Reproduce:
1.Build dev-libs/libpcre-8.45-r1 with USE=jit on big endian aarch64
2.Run "grep -P x /dev/null"
3.
Actual Results:  
$ grep -P x /dev/null
grep: program error
Aborted (core dumped)
$


Expected Results:  
$ grep -P x /dev/null
$

(no crash)

Comment 2 Sam James archtester Gentoo Infrastructure gentoo-dev Security 2022-12-05 00:41:48 UTC
What is using grep -P? I don't think Portage should rely on grep being built with PCRE support, as it's not required by POSIX. I don't see any usage immediately but I didn't look super hard.
Comment 3 Marcus Comstedt 2022-12-05 07:14:56 UTC
It's /usr/lib/portage/python3.10/install-qa-check.d/60pkgconfig which
contains the line

 if grep -qP '=(/usr)?/lib\b' ${f} ; then

    install-qa-check.d/60pkgconfig: remove PCRE
    
    The pattern in question works with both `grep -P` and `grep -E`, prefer
    the latter to avoid having to check if grep is built with PCRE support.
    
        '=(/usr)?/lib\b'
