Bug #: 50137
Summary: [4.7 Regression] ppc64/libstdc++-v3 is miscompiled on
powerpc-apple-darwin9 since revision 177691
Classification: Unclassified

Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: middle-end
AssignedTo: unassigned@gcc.gnu.org

Compiler version: 4.7.0 20110818 (experimental) [trunk revision 177878p2] (GCC)
Platform: powerpc-apple-darwin9.8.0
configure flags: --prefix=/opt/gcc/gcc4.7w
--enable-languages=c,c++,fortran,objc,obj-c++,java,lto --with-gmp=/sw
--with-libiconv-prefix=/usr --with-system-zlib --with-cloog=/sw --enable-lto
--enable-cloog-backend=isl
(where the last two failures are pr47762).
Note that I have to rebuild ppc64/libstdc++-v3 to see the failures disappear;
this is why I think the library is miscompiled.
Would it be possible to infer from the failures what is (are) the file(s) that
is (are) miscompiled?
