Package: clang-3.7
Version: 1:3.7.1-1+b1
Severity: serious
Justification: segfault
Hi,
packaging a new upstream version of afl we've discovered that there's a problem
with current
clang-3.7 on s390x (2.08b-3 build against clang-3.7/llvm-3.7-dev today) [1].
Probe case (provided by Michael Zalewski) tested on s390x porterbox:
<cut>
$ echo 'int main() { printf("%p\n", __builtin_return_address(0)); return 0; }'
> test.c
$ clang-3.7 -g -O2 -fPIE -fPIC test.c
test.c:1:14: warning: implicitly declaring library function 'printf' with type
'int (const char *, ...)'
int main() { printf("%p\n", __builtin_return_address(0)); return 0; }
^
test.c:1:14: note: include the header <stdio.h> or explicitly provide a
declaration for 'printf'

BTW, this is a regression from clang-3.6 (2.08b-1 and -2 have been build
against clang-3.6/llvm-3.6-dev yesterday with same result) [2], so please
reassign or clone that bug report if found suitable.

I am hereby closing bugs in that do not apply to LLVM 3.8 in LLVM 3.7
binary packages that are not shipped in stretch (LLVM 3.7 in stretch
is limited to providing what ghc needs on arm*).
