racc: Failed to build gem native extension

[tkowalewski]

I'm trying to install racc, but when LD_PRELOAD env is set (to /usr/lib/x86_64-linux-gnu/libjemalloc.so.2) error occurs.

Building native extensions. This could take a while...
ERROR:  Error installing racc:

That looks like a bug in gcc to me:

Agree, I'm not sure there's anything we can do in the racc gem that would avoid this from happening.
