0001-sys-apps-grep-2.25-Skip-pcre-jitstack-test.patch (text/plain), 2.23 KB, created by gentoo_usr on 2017-01-06 13:51:43 UTC

Subject: [PATCH] sys-apps/grep-2.25: Skip pcre-jitstack test

The test pcre-jitstack is known to fail if sys-libs/libpcre is build
without JIT. If sys-libs/pcre is build without JIT, then patch the
grep sources to skip this test.
