Bug ID: 71092
Summary: internal compiler error: in cxx_eval_call_expression,
at cp/constexpr.c:1449; only with -Os
Product: gcc
Version: 6.1.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: bugz at 0x83 dot eu
Target Milestone: ---
When compiling the MSP430 debug stack http://www.ti.com/tool/mspds with GCC
6.1.1, I got this error message:
DLL430_v3/src/TI/DLL430/EM/Sequencer/Sequencer430.h: In constructor
‘TI::DLL430::Sequencer430::State::State()’:
DLL430_v3/src/TI/DLL430/EM/Sequencer/Sequencer430.h:60:11: in constexpr
expansion of ‘std::shared_ptr()’
DLL430_v3/src/TI/DLL430/EM/Sequencer/Sequencer430.h:60:11: internal compiler
error: in cxx_eval_call_expression, at cp/constexpr.c:1449
State() { std::fill_n(nextState, NUM_TRANSITIONS, 0); }

Please submit a full bug report,
with preprocessed source if appropriate.
To reproduce, compile the attached file with
g++ -c prep.cpp -Os
With optimisation levels different from -Os, the file compiles just fine, as it
does with GCC 5.3.0.
Sorry for not being able to provide a more concise test case, but I haven't yet
been able to isolate the issue.
