PATCH: [perl #134034] Assert fail in pattern match
This turned out to be a general problem in regexec.c. The function
regtry() can change the position we are looking at in the target string.
In particular it can point to just past the end of the string. Previous
to this commit, we were assuming that the returned string contained
valid data in the returned position, and in many places we assumed that
it was before the end. This commit fixes that in a bunch of places.
