testcase
I'm getting a Segfault when compiling code that instantiates a
std::chrono::time_point<clock> with clock::duration being a struct inheriting
from std::chrono::duration.
When I typedef clock::duration to std::chrono::duration, it compiles fine.
When not using -g, it compiles fine.
Additionally, not sure if this is related, some error in the code or a
different bug:
I typedef'd the std::chrono::time_point<clock>, but when not using the typedef
(so instead write out the type) I get a compiler error about clock not being a
type.
Note that instancing clock::duration does not result in any error.
The attached testcase crashes when compiling with -g (fine without -g).
You can define the NO_CRASH macro to use a typedef to std::chrono::duration
instead of a struct inheriting the type, which compiles fine.
You can also define the C_ERR macro to use std::chrono::time_point<clock>
instead of the typedef, which results in a compiler error.
I used the C++ standard-library from gcc 4.8.1 for this.</pre>
