Summary: SIGSEGV and SIGABRT on large (unsigned-byte 8) arrays 

Initial Comment:
Hi,

this is on clisp-2.49 on linux/x86_64. Offending code:

1)
(let ((a (make-array (truncate array-total-size-limit 8) :element-type '(unsigned-byte 8))))
  (aref *a* 100000))
=> Program received signal SIGSEGV, Segmentation fault.
0x000000000050adbc in storagevector_aref (datenvektor=..., index=100000) at ../src/array.d:537
2)
(let ((a (make-array (truncate array-total-size-limit 8) :element-type '(unsigned-byte 8))))
  (gc))
=> [../src/spvw_garcol.d:1146] assertion failure:
0
0

Program received signal SIGABRT, Aborted.
0x00007ffff6dfea75 in raise () from /lib/libc.so.6

array-total-size-limit is 2^32
Errors do not occur with small arrays or when element-type is T.

Message:
thank you for your bug report.
the bug has been fixed in the CVS tree.
you can either wait for the next release (recommended)
or check out the current CVS tree (see http://clisp.cons.org)
and build CLISP from the sources (be advised that between
releases the CVS tree is very unstable and may not even build
on your platform).
