<pre>Test case like this:
[code]
double d154 = .0'e+1_liters;
[/code]
~/wk.dev$ clang++ --version
clang version 4.0.0 (trunk)
Target: powerpc64le-unknown-linux-gnu
Thread model: posix
~/wk.dev$ clang++ -std=c++11 x.C
x.C:1:17: warning: missing terminating ' character [-Winvalid-pp-token]
double d154 = .0'e+1_liters;
^
x.C:1:17: error: expected ';' after top level declarator
double d154 = .0'e+1_liters;
^
;
1 warning and 1 error generated.
But when we use -std=c++14.
~/wk.dev$ clang++ -std=c++14 x.C
x.C:1:17: error: digit separator cannot appear at end of digit sequence
double d154 = .0'e+1_liters;
