Hello. I am trying this awesome framework. Thank you for this package.

Today, I met an error (sigsegv) with the simple example server. with a nim version from the #devel channel

Hello and thanks for the report. On Nim's devel branch there is an issue with the allocator. The Nim team is aware of this and it'll hopefully be fixed soon. In the meantime I have heard that -d:useMalloc works on devel.
