--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Confirmed.
In GCC 7, GCC didn't crash (with -std=c++17 -fconcepts) but gave a wrong error
message:
<source>:11:24: error: no match for call to '(A<false>) (int)'
int j = A<false>{}(0); // Crash
^
<source>:11:24: note: candidate: int (*)(int) <conversion>
<source>:11:24: note: candidate expects 1 argument, 2 provided
The crash started in GCC 8.

c++: constrained surrogate call functions [PR110535]
We weren't checking constraints on pointer/reference-to-function conversion
functions during overload resolution, which caused us to ICE on the first
testcase and reject the second testcase.

gcc/cp/ChangeLog:
* call.cc (add_conv_candidate): Check constraints.

* g++.dg/cpp2a/concepts-surrogate1.C: New test.
