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: unassigned@gcc.gnu.org
ReportedBy: bruno-gcc@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
Please submit a full bug report,

Let's add Jason in CC about this. Besides PR53989, it seems also related to the
following PR54038.

FYI, when we picked up r194286 into google/gcc-4_7 branch, and ran our 500,000
validation tests, we discovered two instances of mis-compilation.
This code:
typedef vector<void*> T[13];
void foo() {
T x;
...
}
is mis-compiled to omit 13 calls to vector::vector, and x[0], x[1], etc. all
contain uninitialized stack garbage data members.
I've confirmed that trunk compiler is similarly broken.
Unfortunately I haven't been able to reduce the test case that exposes the
problem yet.

It took a whole week, but I finally have reduced test case in PR55804.
