Details:

Don't know if there is really something to care about, but one test fail :

guile: uncaught throw to stack-overflow: (#f Stack overflow #f #f)
FAIL: test-scm-with-guile
==================================
1 of 19 tests failed
Please report to bug-guile@gnu.org
==================================

Using gdb, it apears that the stack-overflow occurs when
calling scm_with_guile(entry_point) the last time before returning from
main().

This issue may already have been present in 1-9-13.

Well, the same happens on amd64 as well.

Follow-up Comment #2, bug #31941 (project guile):

The bug happens because SCM_STACK_OVERFLOW_P erroneously report
a stack overflow, because the base of the stack is not updated
when the thread reenter into guile mode as it's supposed to according the the
patch that's tested
(http://lists.gnu.org/archive/html/guile-devel/2008-11/msg00037.html).

This happens because this code is never executed since the top of
the stack is always NULL.

Grepping through the code, I can't find were the current thread stack top is
ever set.
Apparently all initialization of top is gone with this patch :
45f15cac1f7f36c24ad0734fe128483080272e5f

Making the aforementionned patch dead code.
