Possible regex glitch

[Jerry James]

Does anybody understand the regex code well enough to tell me if the
following scenario can happen?  In regex_tag_multiline(), in src/regex.c
line 6092, we discover that name is the empty string, so we assign NULL
to name.  From there, is it possible to arrive on line 6101 and call
strlen(name)?
