## 3rd party bugs
This section outlines known bugs in 3rd party components (this means compilers, standard libraries, standard runtimes).
### Visual Studio 2015 -- `GENERATE` does not compile if it would deduce char array
VS 2015 refuses to compile `GENERATE` statements that would deduce to a
char array with known size, e.g. this:
```cpp
TEST_CASE("Deducing string lit") {
auto param = GENERATE("start", "stop");
}
```
A workaround for this is to use the `as` helper and force deduction of
either a `char const*` or a `std::string`.
### Visual Studio 2017 -- raw string literal in assert fails to compile
There is a known bug in Visual Studio 2017 (VC 15), that causes compilation error when preprocessor attempts to stringize a raw string literal (`#` preprocessor is applied to it). This snippet is sufficient to trigger the compilation error:
```cpp
