With recent 'grep' you can work around the problem by configuring

Not so. I did a fresh
./boostrap
./configure --with-included-regex
make
and it still core dumps:
$ echo abc | ./src/grep -E '(.*)(.*)(.*)\3\2\1'
grep: regexec.c:1413: pop_fail_stack: Assertion `((Idx) (num) < ((Idx) -2))'
failed.
Aborted (core dumped)
I looked at it in a debugger fs->num before the --fs->num executes looks to
be -1.
Sorry, you're right. I got confused into thinking that grep Bug#22793 and grep
Bug#21513 are the same bugs, but they're not. I have unmerged them.
This is still a glibc bug, not a grep bug; it's just that we don't have a fix.
grep Bug#21513 is indeed fixed by configuring --with-included-regex.
