>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.
