[Users] out of mem during regexp (was: regexp and AVP problem)

[Klaus Darilion]

Hi!

Meanwhile I splitted the regexp into several smaller ones nad now it 
works. But I found an interesting thing when removing blanks from an AVP:

This one works fine:
avp_subst("$avp(s:pai)/$avp(s:painb)","/[[:blank:]]//g");

This one causes "out of mem":
avp_subst("$avp(s:pai)/$avp(s:painb)","/[[:blank:]]*//g");
                                                    ^
