Prior to this, PV was in SV body, and sv_any can be NULL, so accessing SvPVX without checking type on old Perls was a SEGV. Make a note of this so others don't find out the hard way. ----------------------------------------------------------------------- Summary of changes: sv.h | 3 ++- 1 files changed, 2 insertions(+), 1 deletions(-) diff --git a/sv.h b/sv.h index 94ba1e6..fd3da2d 100644 --- a/sv.h +++ b/sv.h @@ -730,7 +730,8 @@ Only use when you are sure SvNOK is true.
