Dropping the -foptimize-sibling-calls (which is implied by -O2) makes it work again. So does using an older version of gcc (e.g. 4.4.3) or running emacs outside a terminal. $ gdb ./src/emacs GNU gdb (GDB) 7.1 Copyright (C) 2010 Free Software Foundation, Inc.

It should have been much smalle. Can you set a watchpoint at the address of row->glyphs[3], and see who puts there a non-null value? Here's how to do that: In the crashed session: (gdb) p &row->glyphs[3] $1 = (struct glyph **) 0x12345678 Start a new session: gdb ./emacs (gdb) start -Q -nw (gdb) watch *(struct glyph **) 0x12345678 (gdb) continue 0x12345678 is of course just an example, you will actually see some other value. You should see one change of the value here (line 673 in dispnew.c): matrix->rows = (struct glyph_row *) xrealloc (matrix->rows, size); bzero (matrix->rows + matrix->rows_allocated, new_rows * sizeof *matrix->rows); The value should change to a NULL pointer. You should then see another change in the loop which starts on line 697 in dispnew.c: for (i = 0; i < dim.height; ++i) The value should change from a NULL pointer to something non-null. There should be some more similar changes. Please see which one of them puts the bogus value 0x7ffff73525fa or some such there. Thanks.

Could you please try to find out where exactly the problem is? You can do a binary search on the object files compiled with the options that result in a working binary by linking them with the ones that result in a non-working binary. Maybe you can find a single file that gets miscompiled, and then find out what function in that file gets miscompiled.
