Something tells me that the gdb output isn't quite right, as the references (buffer) object is the same for all of these: p row->glyphs[area][i-1] (if i > 0) p row->glyphs[area][i] p row->glyphs[area][i+1] .. so why would it fail on [i] but not on [i-1]. My only suggestion to get to the bottom of this is to build emacs without optimizations like this: /configure "CFLAGS=-g -O0" (that's letter O followed by digit 0). make [ alternatively, you can: - cd src/ - edit Makefile changing CFLAGS= line to read CFLAGS=-g -O0 - rm *.o - make emacs ] and see if that makes a difference [it could actually result in finding a different position of the crash...] -- Kim F.
