Summary: internal compiler error: in tsubst_pack_expansion
(triggered by decltype)
Product: gcc
Version: 4.6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: schmidt-thieme@ismll.de
Created attachment 22963
--> http://gcc.gnu.org/bugzilla/attachment.cgi?id=22963
preprocessed source file
gcc (svn rev. 166057) throws an internal compiler error when
compiling the attached file "bug-gcc-compiler-error.ii"
> g++ -std=c++0x bug-gcc-compiler-error.ii
bug-gcc-compiler-error.cpp: In function ‘int main()’:
bug-gcc-compiler-error.cpp:33: internal compiler error: in
tsubst_pack_expansion, at cp/pt.c:7544
The code compiles fine if the definition of "reverse" is replaced
by:
template <template <typename... __ARGS> class _F, typename _T, typename...
_ARGS>
_T reverse (_T x1, _ARGS... args) {
return _F<_T, _ARGS...>::call_function(x1, args...);
}

4.3 rejects the code without ICEing because it doesn't have decltype.
I gather from Jason closing the bug the fix isn't worth backporting.

I tend to be very conservative about ICE-on-invalid fixes on earlier releases,
since the risk/reward ratio seems low. But this one seems safe enough that
I'll go ahead and backport it.
