plog with boost::filesystem::path generates a segmentation fault

[bitFiedler]

Hi,
I tried the latest version because now you support container std::vector and so on.
But there is a problem, if you use boost::filesystem::path and to log the path it crashes with an seg vault.

boost::filesystem::path p("/tmp");
LOGI << "show path: " << p;

with std::cout it's working as expected.

Hi! Let me check that.

[SergiusTheBest]

Indeed! boost:path is missing operator string_type() const that std::path has, so it's processed as a container. I'll add a fix for it.

Thank you for reporting!

[SergiusTheBest]

The issue is fixed!

[bitFiedler]

That was fast.
Thanks for the quick fix.

What I do not understand how the detector works?
Could it be possible that other boost classes do have the same effect by using the wrong formatter?

It checks for presence of preferred_separator field in a class and skip such classes from being treated as containers.

Unlikely. The problem with path is that it goes into the endless recursion: path("/tmp").begin() returns path("/"), path("/").begin() returns path("/"), path("/").begin() returns path("/") and it repeats until stack overflows.
