Bug #: 50623
Summary: Template metaprogramming involving 4
std::complex<double> fails without -std=gnu++0x
Classification: Unclassified
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: giulio.eulisse@cern.ch
Created attachment 25422
--> http://gcc.gnu.org/bugzilla/attachment.cgi?id=25422
reduced test case.
The attached test.cc file provokes an ICE (see below) when compiling it with
c++ -c -O2 test.cc
Notice that changing R to be a double, adding -std=gnu++0x, or making it a 3
vector fixes the problem.
This was done with:
c++ (GCC) 4.7.0 20111001 (experimental)
===
test.cc: In function 'R evaluate()':
test.cc:28:3: error: invalid rhs for gimple memory store
a$_M_value
v1$_M_value
# .MEM_14 = VDEF <.MEM_12>
a$_M_value = v1$_M_value;

Yes, just a misunderstanding with vincenzo on who posts the bug.
