Summary: [C++0x][constexpr] Constant expressions support
reinterpret_cast
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: daniel.krueg...@googlemail.com
CC: ja...@redhat.com
gcc 4.7.0 20110521 (experimental) in C++0x mode accepts the following code:
//---
constexpr const char* c = reinterpret_cast<const char*>(0x123);
//---
As of FDIS 5.19 p2 b13 reinterpret_cast is no longer supported in constant
expressions, therefore the code should be rejected.
I'm emphasizing this because gcc should at least try to implement this to find
out, how much code will break because of this change.
