I don't have that case, there's always text present.

extra is the pcrecpp defaults, { 0, 0, 0, 0, 0, 0 }, startpos is 0,
vec and vecsize are pcrecpp default, too, an array and 51.

No, I work with Windows and we have no tool for that. The Borland
Builder does provide somethign called code guard though, which checks
for and logs errors like memory leaks etc. at runtime. But if I
activate that, the error doesn't occur either. :-(

How do I pass startpos etc. to pcretest? The regex I work with is
^[^\d]*1[^\d]*$ on the subject "1" to check that it's 1. But the error
occurs on any subject or regex, if it occurs, the first time I use
FullMatch because in that case "options" is set.

It can't be options alone, too, because the program did work before
with exactly the same regexes and data. I even I tried to add pcre
completely to the project, not using static libs like before, and the
error occurs, but I can't debug pcre_exec, either.
Looks like I have to do some Voodoo again. :-(
Mit freundlichen Grüßen,
