| | | | | | | | | | | | | | | | * src/keyboard.c (Fposn_at_point): If pos-visible-in-window-p returns a 6-member list for a partially visible glyph, pass the sum of Y and RTOP to posn-at-x-y, since that's where the visible portion of that glyph begins on display. (Bug#24804) (Bug#21832) (Bug#23809)

| * Fix handling of allocation in regex matchingNoam Postavsky2016-10-214-17/+103
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | `re_match_2_internal' uses pointers to the lisp objects that it searches. Since it may call malloc when growing the "fail stack", these pointers may be invalidated while searching, resulting in memory curruption (Bug #24358). To fix this, we check the pointer that the lisp object (as specified by re_match_object) points to before and after growing the stack, and update existing pointers accordingly. * src/regex.c (STR_BASE_PTR): New macro. (ENSURE_FAIL_STACK, re_search_2): Use it to convert pointers into offsets before possible malloc call, and back into pointers again afterwards. (POS_AS_IN_BUFFER): Add explanatory comment about punning trick. * src/search.c (search_buffer): Instead of storing search location as pointers, store them as pointers and recompute the corresponding address for each call to `re_search_2'. (string_match_1, fast_string_match_internal, fast_looking_at): * src/dired.c (directory_files_internal): Set `re_match_object' to Qnil after calling `re_search' or `re_match_2'. * src/regex.h (re_match_object): Mention new usage in commentary.
