Weird bug - Segfault on flipped matrices > 6x6 #172

Closed sasha-id closed 3 years ago

sasha-id commented 3 years ago

Works fine:

m = Numo::Bit.zeros(6,6)
m = m.flipud
m[true, 1] = 1

Segfault:

m = Numo::Bit.zeros(7,7)
m = m.flipud
m[true, 1] = 1
(irb):3: [BUG] Segmentation fault at 0x0000000000000000
