The crash occurs with glibc 2.28 and not with glibc 2.27. Bisecting glibc.git shows glibc-2.28~122 as the first bad commit:

“posix: Sync gnulib regex implementation”

I verified that it was fixed in glibc master (post-2.28) with:

https://sourceware.org/git/?p=glibc.git;a=commitdiff;h=bc680b336971305cb39896b30d72dc7101b62242
“regex: fix uninitialized memory access”

which was backported to the 2.28 stable branch (two commits after the snapshot in cosmic/disco!):

Please add this patch.
