--- Comment #5 from Mikhail T. <mi at ALDAN.algebra.com> ---
I first had this problem, when I built 57.0.2 with clang50 (by overwriting the
then-default compiler).

Now that clang50 is the default, I can not get 57.0.4 to build properly:

 * clang-devel (6.0.0), clang40, clang39 all fail to compile because of syntax
errors (something about Args vs. args, as well as char16_t being a built-in
type)
 * gcc6 and gcc7 compile, but fail to link -- some hideous-looking C++ symbol
not found

clang50 builds the binary, but it fails to start. Unless I build it without
/any/ optimization. I normally use -O2, which crashes. I tried -O1 -- still
crashes. Only by setting -O0 can I get a sort-of usable binary (very slow).

Will try to upgrade clang -- glad to see, it is not my setup...
