Requiring mathn causes Float.to_d to SEG FAULT when used with BigDecimal

Added by mrbauer1 (Matt Bauer) about 12 years ago. Updated about 12 years ago.

Description

To Reproduce:

require 'bigdecimal'
require 'bigdecimal/util'
require 'mathn'

10.0.to_d #=> Generates SEG FAULT (https://gist.github.com/1921116, https://gist.github.com/1921407)

Note only this combination of requires causes the SEG FAULT. If math isn't included, it will work as expected. I confirmed this works in 1.8.7-p249 and 1.9.2-p290 on the same platform.
