Bug #: 56728
Summary: ICE using constexpr initialization and arrays
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: n...@chello.at

code to raise the ICE
gcc 4.8.0 raises an ICE when fed with the provided code, while gcc 4.7.2 has no
problems.
removing either of the constexpr fixes the issue, and one of them probably
shouldnt pass as constexpr in the first place (Im not really adept at
interpreting the official C++11 standard but AFAIR reinterpret casts arent
allowed?)
internal compiler error: in gimple_expand_cfg, at cfgexpand.c:4575
