<pre>The C11 standard only says (N1570 ยง6.10.8.1p1):
| __LINE__ - The presumed line number (within the current source file) of the
| current source line (an integer constant)
As the two invocations of the "inner" macro are originally on two different
lines, I'd say that clang is correct here. I also think that "presumed" leaves
preprocessor implementations a bit of leeway.
BTW: clang is not affected by the GCC bug you mentioned.
I'm closing this bug. Please feel free to reopen if you disagree.</pre>
