<pre>This happens in the LLDB unit tests, when building under windows.
In lldb\unittests\Utility\ReproducerInstrumentationTest.cpp:
LLDB_REGISTER_METHOD(void, InstrumentedFoo, Validate, ());
(...)
LLDB_REGISTER_METHOD(void, InstrumentedBar, Validate, ());
The clashing IDs are evaluated as follows:
&invoke<void(InstrumentedFoo::*)
()>::method<(&InstrumentedFoo::Validate)>::record
and
&invoke<void(InstrumentedBar::*)
()>::method<(&InstrumentedBar::Validate)>::record
Both "record" implementations are only calling Validate() through the vtable,
so the implementations are identical for both.
The linker does COMDAT folding (option /OPT:ICF), which merges the 2 functions,
so their address, which is used as an ID, end up being identical.</pre>
