Ok, here the last working revision:
--8<---------------cut here---------------start------------->8---
changeset: 123952:4d87702c495a
user: Paul Eggert <eggert@cs.ucla.edu>
date: Mon Dec 03 13:07:47 2012 -0800
summary: * bytecode.c, lisp.h (Qbytecode): Remove.
--8<---------------cut here---------------end--------------->8---
And the crash reappear when I compile from here:
--8<---------------cut here---------------start------------->8---
changeset: 123953:342630a53fea
user: Paul Eggert <eggert@cs.ucla.edu>
date: Mon Dec 03 13:42:12 2012 -0800
summary: Don't let call-process be a zombie factory.
--8<---------------cut here---------------end--------------->8---
Hope that help.
