ICE: template.c:806: failed assertion `i < parameters->dim'

[Jacob Carlborg]

I have quite a big project and when I compile it I get this internal 
compiler error: template.c:806: failed assertion `i < parameters->dim'.
I don't know what could cause that error so I don't know where to look 
in my code to try to produce a small test case and report an issue. I'm 
using quite a lot of templates, template mixins and string mixins.

I'm using dmd v1.045, I also get the same error with the latest ldc with 
this backtrace:

deduceFunctionTemplateMatch, file
