you use old lib compiled with older dmd? or using same compiler 
version you update derelict?

anyway here is little tips:
1) every time you update ur dmd do full rebuild since some 
internals of the phobos API may frequently change.
2) do full rebuild anything that was used lib X before and after 
it's updated.

I have tried to rebuild all libraries that i use. Even tried to 
build the project on newly created VM, but result is the same.
Now i decided to try exlxlude files from LibCore until the 
problem disappears, to find the file that causes problem.
Thanks for your answer!

I found where is a bug. It is old magic bug that a have magically 
fixed in the past. But seems that it wont be fixed.

I had writeln statement in my code which was used to display all 
uniforms of the shader program. It can't be removed. When i 
remove it, the error from this topic occurs.
Then i have replaced it with this
writef("",uniforms);
And then i had somehow commented it out. Until now.

Now it seems that after total rebuild this bug has came out 
again. So, just for now i've put stub writeln at the place.

It is magic!!

do you have referenced projects in xamarin? if so, any time you 
change something in one of such projects you need to rebuild 
whole solution, that one of many reasons why i don't use 
xamarin/mono-d

Yes, i have. This moment has started to annoy me. I think 
MonoDevelop has this feature, isn't it? Maybe i should use 
Visual-D.
But this is not important at this moment.
Maybe it is a compiler bug? When i will have enough time, i will 
try to distinguish the code which causes the problem into some 
small piece of code.

this is maybe caused by wrong linker usage, after all mono-d is 
primarily developed for linux?

oh i see you also use -gc, in some cases it can add PITA. simple 
example is ctfe enums. try compile without -gc and -g, if this 
would work then it's really linker or compiler bug.

monodevelop/xamarin is the same crap just after rebranding, it 

it mimics visual studio behavior, and i can confirm that in 
visual-d reference projects works fine, and you also has a 
debugger unlike mono-d O_-

the only disappointing fact is that mono-d has the best code 
completion so far :(
but really for my projects size this is not a big issue.
