Bug ID: 128522
Summary: [17 Regression] ICE on qt-6.12.0: ICE in
redirect_callee, at cgraph.cc:1750
Product: gcc
Version: 17.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: ipa
Assignee: unassigned at gcc dot gnu.org
Reporter: slyfox at gcc dot gnu.org
Target Milestone: ---
Noticed ICE on `gcc-master` against `qt-6.12.0` from r17-6007-g2397b3b0422d72.
I had to apply 2 pending fixes to get to this ICE:
- PR128226
- PR128227
After applying both patches the ICE looks this way:
// $ cat qcbordiagnostic.cpp.cpp
template <typename _Container> auto data(_Container __cont) {
return __cont.data();
}
enum GrowthPosition {};
template <typename C> bool q_points_into_range(const int **, C c) {
bool __trans_tmp_7(data(c));
return __trans_tmp_7;
}
struct QArrayDataPointer;
template <class> struct QPodArrayOps {
QArrayDataPointer *that();
template <typename Args> void emplace(Args) {
GrowthPosition pos;
that()->detachAndGrow(pos, 1, nullptr, nullptr);
}
};
struct QArrayDataOps : QPodArrayOps<int> {
QArrayDataOps *operator->();
};
int ptr;
bool detachAndGrow_detach;
void constAllocatedCapacity();
long size;
struct QArrayDataPointer {
QArrayDataOps operator->();
int *data() {
int p;
[&] { [[assume(p)]]; }();
return &ptr;
}
void detachAndGrow(GrowthPosition, long, const int **data,
QArrayDataPointer *) {
if (detachAndGrow_detach) {
constAllocatedCapacity();
freeSpaceAtEnd();
if (size)
data &&q_points_into_range(data, *this);
}
}
void freeSpaceAtEnd();
} d;
void DiagnosticNotationappendValue() {
d->emplace(d);
d->emplace(d);
}
