[Omake] Invalid_argument("Omake_build_util: internal_error")

[Christopher L Conway]

I'm getting the above error when I try to build my project with omake
0.9.8.1. I can isolate it down to a change I've made in an ML file,
although the error is not a direct consequence of compiling the file
in question. In fact, it seems to crop up between successful shell
invocations (perhaps as the result of some dependency analysis?).

Any insight into what this error means or how to debug it would be appreciated.

Thanks,
Chris
