Does dmd omit framepointers in release buidls? (on windows)
If yes is there a way to turn it off?

Yes.

I think the only option is not to use -release.

(For the record, I also don't think that putting stack frame generation  
and disabling of asserts/etc. behind one option was a good idea.)

That is really unfortunate. I would like to profile my application 
obviously in release build. Because of the omitted framepointer the 
profiler can often not walk the callstack correctly and this results in 
wrong profiling output. Not building with -release would not really 
result in representable results when profiling.

You should try the good built-in profiler.
It's an instrumenting one and besides a severe slowdown in certain
situations the results are way preciser than those from a sampling  
profiler.

As I want to profile a realtime 3d game the builtin profiler is not 
usable for me, as it slows my game down to unplayable framerates. Using 
a sampling profiler however is possible without a gamebreaking 
performance impact.
