[ruby-core:57231] [ruby-trunk - Bug #8879] String#to_r fails after moving ruby to other OSX system

Issue #8879 has been updated by nagachika (Tomoyuki Chikanaga).


Thank you for provide the binary. I can reproduce with it.

It seems that rb_rational_new2(ZERO, ONE) in read_num() return a Fixnum 0 because canonicalization == 1.

I've found that it can be reproduced in trunk with mathn/rational.

$ ruby-trunk -r rational/math -e 'p ".8".to_r'
0

mathn/complex and mathn/rational are extension libraries and statically linked with your binary. But mathn.rb doesn't load automatically because it is a pure-ruby library.
Add require "mathn" fixes this problem in short.

$ ./bin/ruby -rmathn -e 'p ".8".to_r'
(4/5)

I have no idea why the problem is revealed only when the binary is transferred to other system.
nobu, how do you think?

I got reported by users (((<rvm issue 2189|URL:https://github.com/wayneeseguin/rvm/issues/2189>))) that a static binary compiled for OSX after moving to other system fails for the method (({String#to_r})):
 ruby -e 'puts ".8".to_r'
 0
The same binary checked on the build system produces proper result:
 ruby -e 'puts ".8".to_r'
 4/5
Also the same version compiled from source on the target system produces proper result:
 ruby -e 'puts ".8".to_r'
 4/5
Please help me debug the problem, can it be related to compilation with (({clang}))?
