Bug ID: 100517
Summary: [12 Regression] ICE in rvalue, at cp/tree.c:946
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Keywords: ice-on-invalid-code
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: asolokha at gmx dot com
Target Milestone: ---
g++-12.0.0-alpha20210509 snapshot (g:5e0236d3b0e0d7ad98bcee36128433fa755b5558)
ICEs when compiling the following testcase, reduced from
test/SemaCXX/vector-casts.cpp from the clang 11.1.0 test suite:
typedef int __v2si __attribute__ ((__vector_size__ (8)));
struct S { };
void
f (S s)
{
(void) reinterpret_cast<__v2si> (s);
}
% g++-12.0.0 -c jtptvwic.cpp
jtptvwic.cpp: In function 'void f(S)':
jtptvwic.cpp:8:37: internal compiler error: in rvalue, at cp/tree.c:946
8 | (void) reinterpret_cast<__v2si> (s);
