i crash with again this error in alloc.c:

,----
| Program received signal SIGSEGV, Segmentation fault.
| 0x0817513d in mark_object (arg=142015006) at alloc.c:5487

before it was

I can crash at everytime now using the same command that recurse
through a big tree and match regexp in file (like rgrep but all lisp).

This same command work fine in 23.2 (on same conditions of course).

But as i said in precedent posts, i can crash also doing simple things
e.g next-line in any buffer.
