Bug #10438

Updated by nobu (Nobuyoshi Nakada) about 7 years ago

I am trying to make ruby 2.1.4 on a Mac 10.8.5 and the call to miniruby to update rbconfig.rb hangs. 

 When I attach to the process using gdb, the stack is:

   gdb then produces an infinite stack until gdb core dumps (which I assume is a bug in gdb)
