Bug ID: 67155
Summary: Linking of complex constexpr static class member
failing across files

Component: c++

test case
I encountered a strange behavior when creating a class that wraps a constexpr
string.
It seems that the static constant string field wrapped in a class is only
accessible in the same header file and not available in a separate compilation
unit.
The workaround is to move the usage of the static fields into the header.
If you prefer git you can find the test case here as well :
