Bug ID: 61164
Summary: GCC 4.9.0 fails to build libitm with fortification
enabled
Product: gcc
Version: 4.9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libitm
Assignee: unassigned at gcc dot gnu.org
Reporter: rhill at gentoo dot org
We enable -D_FORTIFY_SOURCE=2 by default, but with 4.9.0 we're encountering an
error while building libitm. It can be reproduced without modifying the
compiler by configuring with:
CXXFLAGS="-O2 -g -D_FORTIFY_SOURCE=2" ../dist/gcc/gcc-4.9.0/configure
--enable-languages=c,c++ --disable-werror --disable-bootstrap
The error is:

Comparing the preprocessor output for util.cc and a couple other C++ files that
use vfprintf the most obvious difference is the declaration is missing
__inline, ie.
extern __attribute__((always_inline)) __attribute__ ((__gnu_inline__))
__attribute__ ((__artificial__)) int vfprintf
instead of
extern __inline __attribute__ ((__always_inline__)) __attribute__
((__gnu_inline__)) __attribute__ ((__artificial__)) int vfprintf

I have the same build error.
The build error is reproduced with Linaro GCC 4.9 2014.06 release.
Also switching off -D_FORTIFY_SOURCE=2 helps.
