bignum too big to convert into `long' (RangeError)

[Souravgoswami]

Description

When I have a SAVE_HISTORY value specified to ~/.irbrc in Bignum, for example:

{
	USE_COLORIZE: false,
	SAVE_HISTORY: 10 ** 19,
	VERBOSE: true,
	SINGLE_IRB: true
}
.each { |x| IRB.conf[x[0]] = x[1] }

I can run IRB successfully, but the problems that I face:

1. IRB crash during exit:

Traceback (most recent call last):
	10: from /usr/bin/irb:23:in `<main>'
	 9: from /usr/bin/irb:23:in `load'

2. No histories are saved.
3. All the previous histories in ~/.irb_history are wiped out.

Although I think the length of a number to become Bignum depends on the system (like 64bit vs. 32bit), but eventually it can crash irb, but it shouldn't happen, for example, take a look at .bashrc, you can have values like:

export HISTORY=`ruby -e "print 10 ** 5_000"`

Are you using ~/.irbrc and ~/.inputrc?
Yes, take a look above ;)
