Summary 0005056: Crash - sweep failed to find exact end of memory
Description When executing:

| a b |
a := FloatArray new: (16 * 1024*1024).
b := FloatArray new: (16 * 1024*1024).
[a += b] timeToRun.

I receive a stack dump:
"sweep failed to find exact end of memory"

3.9-7058 image
Linux 3.9-7 VM. I tried with the 3.7-7 VM and it bombed too.
kernel: 2.6.16-1.2080.16.rrt.rhfc5.ccrma

Note Andreas said to Avi in a Sep12 Squeak-dev msg regarding similar error:

"I think you're seeing the old problem of signed vs. unsigned ints when
accessing memory locations (the negative numbers seem to indicate that
much). Try a later VM (3.9-7 is the latest according to SqueakVM.org) -
IIRC, then this problem got fixed in later versions."
Additional Information Full stack dump:
