Bug#798111: Illegal instruction after compiling some code

[Julien Puydt]

Package: clang-3.8
Version: 1:3.8.0~svn245286-1

I tried to compile flint 2.5.2 (http://flintlib.org -- or the orig 
sources of experimental's flint package) with this version of clang to 
check if a problem I had with gcc 5 was compiler-related, but it gave me 
other problems : it compiled the lib and some tests ok, but when trying 
to actually run those tests, I had failures "Illegal instruction".

Using clang version 3.5.2-2 (tags/RELEASE_352/final) (based on LLVM 
3.5.2) gave the same result, but I prefer reporting on the last version.

I configured the sources like this:
CC=clang-3.8 ./configure --prefix=/usr --with-ntl 
CFLAGS='-D_FORTIFY_SOURCE=2 -g -O2 -fstack-protector-strong -Wformat 
-Werror=format-security'

I hope it helps,
