> Looks like GC sometimes kicks in while we are inside re_search_2
Or not. I cannot get a breakpoint inside GC to fire while we are in
search_buffer_re, so maybe my hypothesis was wrong. Although the
symptoms are all there: when the segfault hits, the pointers passed to
re_search_2 are invalid, but BEGV_ADDR and GAP_END_ADDR, from which
they are supposed to be computed, are valid (and different). And the
patch does seem to avoid the segfaults. But maybe it's just a
coincidence or a side effect...
