[BUG] Crash running Borasky's MatrixBenchmark to size 64
Reported by Charles Oliver Nutter | January 23rd, 2008 @ 02:11 AM | in 1.0 preview
The next test will run about 8 times (or more) as long as the last one.
Just "Enter" to continue, or enter a non-empty string to quit:
Hilbert matrix of dimension 64 times its inverse = identity?
An error has occured: Bus violation (SIGBUS) (10)

Quite the speed improvement, too. Good times.
