Bug #19284
closedInteger overflow when using RUBY_GC_HEAP_INIT_SLOTS environment variable
Description
If you set the environment variable RUBY_GC_HEAP_INIT_SLOTS
to anything other than 0
, an integer overflow runtime error occurs:
RUBY_GC_HEAP_INIT_SLOTS=10000 ruby -e 'puts "hello, world!"'
# => ruby: integer overflow: 3689348814741910508 * 8 > 18446744073709551615 (RuntimeError)
At this time, I'm not sure if this is platform-specific, but it's failing on Darwin as well as Heroku's environment (Linux).
