Hi,
The last buildd failed on m68k ending on:
ocamlmktop -I . -I +labltk -I ../../src -o lablgltop \
labltk.cma lablgl.cma togl.cma
make[2]: *** [lablgltop] Segmentation fault
make[2]: *** Deleting file `lablgltop'
make[2]: Leaving directory `/build/buildd/lablgl-1.01/Togl/src'
Thanks to Ingo Juergensmann I've been able to get an account on an m68k
box. I first ran gdb to know were was the problem:
arrakis:~/lablgl/lablgl-1.01/Togl/src% gdb ocamlrun
(gdb) r /usr/bin/ocamlc -linkall toplevellib.cma -o test -I . -I
+labltk -I ../../src labltk.cma topstart.cmo
[...]
Program received signal SIGSEGV, Segmentation fault.

I then recompiled tk8.4 with debugging symbols and the segmentation
fault became a bus error:
Do you know if other tk8.4 program worked fine or not ?
No, I don't usually use such oldies as m68k :)
Maybe we could disable lablgl+togl on m68k for now ?
We could but the problem seems to be also affecting caml (see #327746).
I'd rather wait and see if some gcc/m68k/tk/whatever guru has some
insight on this.
Cheers,
Sam.
