[Roderich Schupp]

Source: llvm-toolchain-3.5
Version: 1:3.5.2-1~exp1
Severity: important

Trying to actually build llvm-toolchain-3.5/1:3.5.2-1~exp1 with gcc-5:

....
Using gcc:
gcc-5 -v
Using built-in specs.
COLLECT_GCC=gcc-5
COLLECT_LTO_WRAPPER=/usr/lib/gcc/x86_64-linux-gnu/5/lto-wrapper
Target: x86_64-linux-gnu
Configured with: ../src/configure -v --with-pkgversion='Debian 5-20150321-1'
....
Thread model: posix
gcc version 5.0.0 20150321 (experimental) [trunk revision 221551] (Debian
5-20150321-1)
....

Build stops with:
