10:35:49 drmeister Is sbcl AREF safe by default? Will it always signal an error if I write beyond the limits of an array? I'm working with lots of large arrays and I'm getting memory corruption and crashes with sbcl. I have set --dynamic-space-size to 32768

11:01:01 drmeister I run a little test and I can't aref out of bounds. But I reliably get this...

11:02:17 drmeister I am using lparallel:pmap with 10 threads, but the threads are reading from a common array and writing to separate arrays.

12:28:40 bike drmeister: i think sbcl inserts bounds checks as long as safety>0

13:01:05 yitzi bike: #1627 is ready for a look when you have time.

13:12:53 bike wow. that's the whole problem? i guess it's nice when it's easy

13:13:03 yitzi True

13:15:01 yitzi I might try to fix MAP.ERROR.11 which would involve getting MAKE-SEQUENCE to understand things like '(or (vector t 5) (vector t 10))
