Description
I have the piece of code crashing reliably.
#!/usr/bin/env ruby
require 'openssl'
p = 65997564567567456745676645367739412743227643334286989217363396439283464537000853588029739004855929104754800897261407081024749574299035313695899693187167
def mything(h)
b = 43554325436535756
k = h.to_bn.mod_exp(b, p)
end
h = 3007963317613531062721539798844764834140098543127007866692410407137612395983233591022449771190189492227443776860661459473931676217894527075146085609662899
puts mything h
I have written very similar pieces of code before without an issue but this but particular one seems to have hit something. I have attached a crash report.

The minimal reproducer:
123.to_bn.mod_exp(456, nil)
