Subject: Avoid bogus internal error reporting duplicate In-Reply-To IDs.
X-Git-Tag: 0.1~295
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=64c8d6227a90ea6c37ea112ee20b14f16b9b46e7;p=notmuch.git

Avoid bogus internal error reporting duplicate In-Reply-To IDs.

This error was tirggered with a debugging build via:

	make CXXFLAGS="-DDEBUG"

and reported by David Bremner. The actual error is that I'm an
idiot that doesn't know how to use strcmp's return value. Of
course, the strcmp interface scores a negative 7 on Rusty Russell
ranking of bad interfaces:
