Package: clang
Version: 1:3.2-19
When compiling the current nightly snapshot of Ruby (a copy is available
at https://tilde.snt.utwente.nl/~herwin/ruby-snapshot-20130713.tgz)
using clang it fails at bignum.c. Compiling with gcc (4.8) works fine.
Steps to reproduce:
- Download and untar the source code (link above)
- configure using clang: CC=`which clang` ./configure
- make
compiling bignum.c
