(In reply to Sam James from comment #2) > > regcomp.c is in gnulib. gnulib's corresponding test fails too: > > # ./test-c-stack > test-c-stack: program error > Segmentation fault (core dumped) Given this, the upstream maintainers naturally said to pass it on to gnulib.

(This seems to be because of an older copy of gnulib in that version.) It seems too risky to to backport gnulib changes to grep 3.5. [Note that I ended up discovering an independent issue because filename-lineno.pl failed on sparc too. This ended up being a real bug in that libpcre upstream doesn't support JIT on sparc64 which manifested in both the test failing and e.g. grep -P foo dying with SIGBUS. I've therefore masked dev-libs/libpcre[jit] on sparc64 in fd573f4.] URL: https://lists.gnu.org/archive/html/bug-gnulib/2021-02/msg00002.html URL: https://debbugs.gnu.org/46227 Bug: https://bugs.gentoo.org/673524 Closes: https://bugs.gentoo.org/768135 Signed-off-by: Sam James <sam@gentoo.org> Signed-off-by: Lars Wendler <polynomial-c@gentoo.org> sys-apps/grep/grep-3.5.ebuild | 15 ++++++++++++--- sys-apps/grep/grep-3.6.ebuild | 15 ++++++++++++--- 2 files changed, 24 insertions(+), 6 deletions(-) Additionally, it has been referenced in the following commit(s): https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=bb99c571a3f0c15a69a586b85832f5d5b115718c commit bb99c571a3f0c15a69a586b85832f5d5b115718c Author: Sam James <sam@gentoo.org> AuthorDate: 2021-03-19 23:24:25 +0000 Commit: Lars Wendler <polynomial-c@gentoo.org> CommitDate: 2021-03-22 08:57:43 +0000 profiles/arch/sparc: mask sys-apps/grep[static] for now dev-libs/libsigsegv lacks USE=static-libs and there's really no pressing need to add it for now.
