--- Comment #2 from Markus bergholz  ---
I've no idea how to use `pcretest` from Input file.

cat xlsread.m | pcretest 

seems to be completly wrong. When just starting pcretest, I can enter the
regular expression, but then I dunno how to enter all lines of my file in the
data> section (I need multiple-line matche to hit it I guess).

cat xlsread.m | pcretest 

should work OK, if xlsread.m contains suitable pcretest input. "man pcretest"
documents the format, but it is quite simple, just lines of the form

/somepattern/[]
a data subject to match
another data subject to match

[]

/another pattern/
more data
...

Looking at your code, it looks as though you are searching an entire file. This
is harder to arrange in pcretest, as it all needs to be in one line, with \n
for each newline. I have now done this, and reproduced your crash in pcretest.
Now I can start trying to figure out what is happening. Incidentally, in the
new API version of PCRE (called PCRE2) this example does not crash. Although
development is concentrated on PCRE2, we are still fixing bugs in PCRE1, so
unless this is totally impossible, I should be able to fix it.

I'm afraid I know nothing about GNU Octave and how it uses libpcre. I have
tried to reproduce errors using the pcretest program, and cannot do so. Can you
try putting your test pattern into pcretest and see if it crashes there? A
simple test with [\]\) correctly gives a compiling error for a missing ]
terminator.
