I don't think we can trust any crash backtraces from the 64-bit
Cygwin-w32 builds until we understand what happens with the assertion
violations in bidi.c.
Let's try anyway (assuming you still have this in a debugger):
> #0 0x0000000100650249 in composition_update_it (cmp_it=0x226a98, charpos=1819, bytepos=1819, string=4306700338) at composite.c:1322
> cmp = 0x226240
> i = 0
> c = 2272050
Please show what these commands print in GDB:
(gdb) frame 0
(gdb) p *cmp
(gdb) frame 1
(gdb) p it->cmp
(gdb) p it->current
And I imagine that your buffer was pure-ASCII (is that right?), so no
compositions are involved and we probably shouldn't be even entering
composition_update_it at all.
