--- Comment #2 from Andrew Sutton <andrew.n.sutton at gmail dot com> ---
This was caused by not checking that current_template_parms was valid during
when building constraints for the declaration.

This is was fixed in the last commit (221280).

Seems to me that return requires() as yet does not do "type requirement"

--- Comment #54 from Ian Lance Taylor <ian at airs dot com> ---
I assume that it works on x86 because subtracting 1 from PC in libbacktrace,
and then subtracting 1 again in runtime/pprof/pprof.go, still gives you a PC
within the call instruction.  On PPC, subtracting 1 in libbacktrace and then
subtracting 4 in pprof.go gives you a PC in the instruction just before the
call instruction.

I appreciate that you only want to fix what is broken, but in this case I think
we should turn that around and keep the code simple unless we find that it
breaks something.

Yes, you're right that if we were to change libbacktrace it would mean passing
the flag through a chain of functions.  Basically the flag would have to move
along with the PC value.  I'm not sure this is worth doing, ip_before_insn is
always false except when tracing back through a signal trampoline, where the
file/line information is generally not helpful anyhow.

I needed to push the relevant changes to Origin, which I just did.

Confirming that origin library and the gcc (c-concepts) built with no errors.


make test
1 test failed out of 60
     58 - test_range_algo_none_of (OTHER_FAULT)

seems expected

It(none_of.cpp) fails because the test is copied form all_of.cpp 
  bool pos(int n) { return n > 0; } // '>' should be changed to '<'
