[PATCH] D132944: [clang] cleanup -fstrict-flex-arrays implementation

[James Y Knight via Phabricator via cfe-commits]

jyknight added a comment.

  #include <stdio.h>
  #include <source_location>
  
  
  consteval int fn(std::source_location sl = std::source_location::current()) {
    return sl.line();
  }
  
  consteval int fn2(int line = fn()) {
    return line;
  }
  
  int main() {
    printf("fn=%d fn2=%d\n", fn(), fn2());
  }

I believe this should print `fn=14 fn2=14`. I don't see how we can get that by 
special-casing calls to `std::source_location::current`, and indeed, with this 
version of the patch, the program instead prints `fn=14 fn2=9`.
