Compiler build error

[Alex]

I'm a little bit confused by following situation:

I have code, say around 8000 lines. Now, I'm facing a build error 
which just says

dmd failed with exit code -11,

(same for ldc2, with some lines of stack information, which do 
not belong to my code)

0  ldc2                     0x0000000106fcc4e7 
llvm::sys::PrintStackTrace(llvm::raw_ostream&) + 37
1  ldc2                     0x0000000106fcb9ea 
llvm::sys::RunSignalHandlers() + 83
2  ldc2                     0x0000000106fcc90e SignalHandler(int) 
+ 239
3  libsystem_platform.dylib 0x00007fff5992af5a _sigtramp + 26
4  libsystem_platform.dylib 0x000000015fcde600 _sigtramp + 
104543936
ldc2 failed with exit code -11.

As I'm compiling rather often, I know exactly which line in my 
code causes this error. As the compiler refuses to exit normally, 
I'm not sure, if the line is buggy (so, whether I'm trying to 
compile, something, what is not compilable) or, I'm facing an 
ICE. In both cases, I'm ready to rewrite my code a little bit to 
get around the error, as I need a solution quite fast.

My assumption is, that I built a kind of loop, which the compiler 
does not know how to get along. But in order to rewrite it, I 
have to know, what I have to rewrite... So, despite I know 
exactly the culprit line in my code, I don't have any information 
about how to solve the problem.

What I'm trying now is to use dustmite. But this, lasts for about 
8 hours now and is already at depth 20. Lacking experience with 
this tool, I'm not sure, if this is normal... The last time I 
tried to use it elsewhere, I got a final depth of 13, but also an 
empty file as its analysis result.

The command for dustmite was
dub dustmite ../dust --compiler-status=-11 --combined

Yes... the builds were also done with dub. So,
dub build
and
dub build --compiler=ldc2
respectively.

Any help is appreciated :)
