Did you try building it without the debug flag beforehand? If so, did you run make clean before rebuilding it with DEBUG=true?

[rghvdberg]

I tried (and succeeded) building it without the debug flag beforehand, and ran make clean before rebuilding. I was just curious if the debug build would show any useful messages.

[pdesaulniers]

I'm pretty much sure the issue is with make clean not picking up all of the garbage. I'll take a look at this in a few hours.

Also, I don't log anything interesting in the debug version :)

[pdesaulniers]

This should be fixed now. Can you confirm?

[pdesaulniers]

I can't reproduce this anymore, so I'll assume this is fixed.
