Bug #: 55032
Summary: [4.7 Regression] Internal compiler error: in
strip_typedefs, at cp/tree.c:1199
Classification: Unclassified
Product: gcc
Version: 4.7.2
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: bruno-...@defraine.net
Some variations of bug #53989 still seem to exist (or gcc 4.7.2 does not
contain a complete fix for that bug).
$ cat Test.cpp
template<typename T>
struct vec3t {
T c[3];
};
typedef vec3t<float> vec3;
class Bounds {
public:
Bounds(const vec3 bb[2]);
void foo(const vec3 & v) { v.c[0]; }
};
template<typename T>
void work(T& value);
void foo() {
vec3 bb[2];
work(bb);
}
$ g++ -Wall -c Test.cpp
Test.cpp: In member function 'void Bounds::foo(const vec3&)':
Test.cpp:11:38: warning: statement has no effect [-Wunused-value]
Test.cpp: In function 'void foo()':
Test.cpp:19:10: internal compiler error: in strip_typedefs, at cp/tree.c:1199
