Hi,
I am working on a project for school in which I use afl to find bugs in
software and I decided to fuzz grep. In doing so I discovered a
segfault. When using gdb, the location of the segfault varies, which
puzzles me and so I cannot include any further information.
The command to obtain this bug is:
grep -o -E -f <seg-file>
where <seg-file> is the file attached.

I am using grep 3.1 on arch linux.
cheers
Jeremy
