Public bug reported:
(I hope I was able to classify the bug correctly)
I am for various reasons implementing a C-printf format specifier as a
constexpr function in order to be able to parse format specifiers during
compile-time.
This causes an internal compiler error in clang.
This is somewhat of murky code so it's unclear if I managed to do it
100% ISO C++14 but I think most can agree the compiler shouldn't crash.
For what it's worth the same code works in GCC.4.9.2.
Attached the source + scripts.
Thanks in advance.
Mårten
PS. Any suggestions for work-arounds or corrections accepted gratefully.
