| | | | | | | MUTABLE_SV() check. Use SvPVX_const() instead of SvPVX() where only a const SV* is available. Also fix two falsely consted pointers in Perl_sv_2pv_flags(). p4raw-id: //depot/perl@34770
* SvPV() does not take a const SV*, which means that the pattern argumentNicholas Clark2008-10-301-1/+1
| | | | | | | | | | to Perl_re_compile() can't be const, which means that the pattern argument to Perl_pregcomp() can't be const, as can't the argument in the function in the regexp engine structure. It's a shame that no-one spotted this earlier. (Again) I may have rendered the documentation inaccurate. p4raw-id: //depot/perl@34672
