Umm ... I have pushed changes up to the needed patch to the repo.

The commit 91edcc55c681 "autofs-5.1.7 - use default stack size for
threads" is the one your after.

For this change I also had commit 7f711c687d41 "autofs-5.1.7 -
eliminate some more alloca usage" but I don't think it's actually
needed.

The original problem was due to glibc usage of alloca(3) when getting
group information for very large groups seen on Windows DCs IIRC. But
for some time now glibc doesn't do this any more so all should be ok
without the second patch.

Clearly you'll get a conflict on the CHANGELOG if you don't have all
the preceding patches from the repo. which is straight forward to fix.
