I think should remove it from document

wasamasa commented 5 years ago

What exactly is the problem? Please provide a reproduction because I cannot reproduce this error. If it only happens for you, feel free to not use max-positive-fixnum.

tboevil commented 5 years ago

I mean, this number in the document is too big. Unusable in 64-bit systems will cause problems for some newcomers (such as me), so I suggest to modify the documentation.

wasamasa commented 5 years ago

It works perfectly fine in my 64bit system. Again, please show that there is a problem for other people than just you by providing reproduction instructions.

wasamasa commented 4 years ago

Closing due to lack of a reproducer.

bricewge commented 4 years ago

I have the same issue here too. I can provide more info if need be.

EDIT: #21 is the same issue.

wasamasa commented 4 years ago

I don't believe it's the same issue because you link to a vastly different issue that I've fixed two years ago. Please open a new thread with a full reproducer.

bricewge commented 4 years ago

Sorry I was referencing to #29.

wasamasa commented 4 years ago

Same thing really, this is an issue I fixed long time ago.
