I'm testing a few "real world" regex's from regexlib.com.

This "dutch-style phone number" regex does not match "023-5256677" but it should.

(^+[0-9]{2}|^+[0-9]{2}(0)|^(+[0-9]{2})(0)|^00[0-9]{2}|^0)([0-9]{9}$|[0-9-\s]{10}$)

It works on these:

Matches
+31235256677 | +31(0)235256677

Non-Matches
+3123525667788999 | 3123525667788 | 232-2566778

Hi,
I am just evaluating a small C regex library and found your project. Thanks for that project!

However, I have a problem, that the matching process crashes:

Assertion failed: (R->captures[ 0 ][1] != RX_NULL_OFFSET), function srx_MatchExt, file sgregex.c, line 1218.
' like 'GET|POST'+Abort

You can reproduce this, if you add the following line in sgregex_test.c in the MATCHTEST section:

MATCHTEST("GET /index.html HTTP/1.1\r\n", "GET|POST", 1);

If you add group parentheses, it works:

MATCHTEST("GET /index.html HTTP/1.1\r\n", "(GET|POST)", 1);

Although "GET|POST" is a valid regex, it crashes.

Thanks for your support.

This "US currency" regex does not match "$1,234,567.89" but it should.
^$([0-9]{1,3}(,[0-9]{3})*|([0-9]+))(.[0-9]{2})?$

It works on these:

Matches
$0.84 | $123458

Non-Matches
$12,3456.01 | 12345 | $1.234
