Bug ID: 96354
Summary: [10 regression] ICE in
maybe_canonicalize_mem_ref_addr, at gimple-fold.c:4903
Product: gcc
Version: 10.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: t...@dev-zero.ch
Target Milestone: ---
Unfortunately I wasn't able to isolate it (yet), but what I see with the
plumed-2.6.1 package from https://github.com/plumed/plumed2/releases with
gcc-10.2.0 (which should include the fix for issue #94216 already) is this:
during IPA pass: inline
RMSD.cpp: In member function ‘void
PLMD::RMSDCoreData::doCoreCalcWithCloseStructure(bool, bool, PLMD::Tensor&,
PLMD::Tensor&, std::array<std::array<PLMD::TensorGeneric<3, 3>, 3>, 3>&)’:
RMSD.cpp:1134:6: internal compiler error: in maybe_canonicalize_mem_ref_addr,
at gimple-fold.c:4903
1134 | void RMSDCoreData::doCoreCalcWithCloseStructure(bool safe,bool alEqDis,
Tensor & rotationPosClose, Tensor & rotationRefClose,
std::array<std::array<Tensor,3>,3> & drotationPosCloseDrr01) {
