When I try your test program, the output I get is:
error:regcomp:unknown error code
Segmentation fault
The segfault is not surprising - if the compile fails, you can't expect
the exec to work. Your program ploughs on, even after a compile error,
when the value of regexp will not be valid.
Now, there obviously is some problem there, because "unknown error code"
is not right. Testing your pattern with pcretest, I get
"Pp\,-`],6QdE=%(bbjg8=g5DZao4D8^fM'I/>#Pw]XSjiFI@(?+a2l#t*1(HDA"
Failed: digit expected after (?+ at offset 51
This should end up with a BADPAT error from regcomp. Looking at the
code, I see that there is an error in the tables that handle compile
errors. I'll fix it for the next release, but I don't see it as hugely
urgent.
But now the question remains: why is there no "error:regcomp:..."
message in the output you posted?
Regards,
Philip
