Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org

Given the following test program:
//----- test.cc
typedef float float4 __attribute__((__vector_size__(16)));
typedef long double float8 __attribute__((__vector_size__(32)));
void foo (float4 f4) { }
void bar(float8 f8) { }
//----- end test.cc
GCC 4.8.2 on my Ubuntu crashes with the following message
