Bug 187385 – sys-apps/grep-2.5.1a-r1 crashes (core dump) with attached test case

• Status: RESOLVED WORKSFORME
• Product: Gentoo/Alt

[Description Joe Peterson (RETIRED) 2007-08-01 14:47:31 UTC]

The grep utility dumps core when run with the attached script.  The crash (with this test case) happens on Gentoo/FreeBSD but not Gentoo/Linux.  Note that a long list of text lines are fed to "grep -F".

test case (bash script)

This bash script invokes the crash on Gentoo/FreeBSD.  I have not tried other versions of grep, so I do not know if this is specific to the stated version or not.

Note that the UTF-8 locale seems to be required to make grep crash in this way, so set LANG to en_US.UTF-8 (or en_GB.UTF-8, if you prefer) before running the test script.  The code around the crash site deals with multibyte chars, which clued me in to this.

There is also a bash bug that only occurs on FreeBSD (both Gentoo and vanilla) that is related to UTF-8 - not sure if this is related.

My locale is set to en_GB.UTF-8 and I'm not seeing this crash
