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,
