Yes (AFAICT).

I'm not sure whether your patch is correct because with it applied, it fails
100% of the time at
        grep 'ight foo' aclocal.m4
I think you really meant acinclude.m4 instead of aclocal.m4 ?

Anyhow, if we ignore your patch for the time being, I think the following
diff of "testSubDir" between success and failure runs will make it clearer
where the failure is:
