Test threading_spec.rb fails on armel

I packaged ruby-libv8 and ruby-therubyracer for Kali Linux (a Debian derivative) to work around the fact that the respective gem fails to build on armel/armhf. I have now patched ruby-libv8 to build with -fPIC and thus got a seemingly working ruby-libv8 on all architectures.

Now I tried to build ruby-therubyracer and it builds & works everywhere except on armel where it builds but one of the tests fails (at least with ruby1.9.1 that we use):

................................F.ERROR: Test "ruby1.9.1" failed. Exiting.

The bit of source code mentionned comes from spec/threading_spec.rb so I assume that this is the failing test. The build enviroment is Kali Linux on armel, which is very close to Debian 7 Wheezy on armel.

if you want me to try to reproduce something or to try out some patch, just let me know.

rubyjs / therubyracer
