I got this error when I tried to compile C file (~81Kb) with the -o flag. Without the flag it compiles fine. This wasn't a problem for some earlier DMC versions (v8.40 I think). Aside from this the compilation time was more than 30s in the earlier versions.

DMC v8.46.5n

PS. I can't send the source code.

In addition:
With -o-liv flag instead of -o it compiles fine, although the compilation time is ~67s (on my PC).
With -o-liv-loop the compilation time is ~1s.

There's really not much I can do without an example that can be traced through the optimizer to see where it is going wrong. Try cutting the source file down to a smaller one, nearly all bugs can be reduced to just a few lines of code.

I can’t trace the bug by this way. I stripped the source file to about 2900 lines. If I comment one more line (no matter where) it compiles (almost always) fine.

I can confirm this. Even removing comments may do the trick! Really!

I have a test case from about 5000 lines.

Then send me that (hopefully, the shorter one <g>).

Fortunately, Stefano was able to send source code that reproduced the problem, and the fix is now up in the beta section.

Whow that is quick! Thank a lot! It started to show up frequently.
