The re module is buggy is rare cases; see attached example script. The bug is caused by the macros LASTMARK_SAVE and LASTMARK_RESTORE which are sometimes used without the extra code that does if (state->repeat) {mark_save()/mark_restore()}. The bug appears by mis-reporting the position of groups within a repeated match (with * or +), notably the position of some groups that matched in older repetitions but (after some backtracking) not in newer ones.
