Based on the location of the error, I'd guess it's to do with passing a 
delegate to a templated function / as a template argument. (but it's 
possible it's not a delegate)

To find the error:
- Run dmd with '-v', it should tell you which function it was compiling when 
it crashed (the last one it lists).  Once you know the function it should be 
easier to determine which bit of code causes the crash.
- Or use dustmite to reduce the test case.
