UB in static variables initialization

[astepanov83]

codec::CRLF is initialized in codec.cpp
mime::END_OF_LINE is initialized in mime.cpp and depends on codec::CRLF
I exactly ran into a situation where CRLF was \r\n, but END_OF_LINE was empty

Hi,
Thanks for the reporting. I believe the root cause is also reported here.

[astepanov83]

Yeah, I also changed it to static linking + openssl static linking. Might have caused problems as well

[karastojko]

Yes, the static linking seems to manifest the issue. The dynamic one does not suffer so far, but it has to be fixed anyway. Commits before 1f07964 seems not to suffer of the issue, so you can use an older version until I fix this one.

@astepanov83 Please check the latest commit, it works for me in both static and dynamic linking.
