Bug#679914: llvm-gcc-4.6: Incompatible plugin version, can't compile C

[Vincent Lefevre]

Package: llvm-gcc-4.6
Version: 3.1-1
Severity: grave
Justification: renders package unusable

llvm-gcc can't compile even simple C programs such as

int main (void) { return 0; }

I get the following error:

$ llvm-gcc tst.c
Incompatible plugin version
cc1: error: fail to initialize plugin /usr/lib/gcc/x86_64-linux-gnu/4.6/plugin/dragonegg.so

even though llvm-gcc-4.6 and dragonegg-4.6 have the same version 3.1-1
(current unstable).
