Bug ID: 58633
Summary: [4.7/4.8/4.9 Regression] ICE with decltype of
destructor call
Product: gcc
Version: 4.9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: reichelt at gcc dot gnu.org
The following valid code snippet (compiled with "-std=c++0x") triggers an ICE
since GCC 4.7.0:
================================
void foo(int i)
{
typedef int I;
__decltype(i.I::~I())* p;
}
================================
bug.cc: In function 'void foo(int)':
bug.cc:4:22: internal compiler error: in cp_parser_abort_tentative_parse, at
cp/parser.c:24356
__decltype(i.I::~I())* p;
