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

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 :)

Ok. Dustmite finished. But the result is again an empty file... :(

Is this the entire stack trace? If dmd is also affected chances 
it is a frontend bug.

A complete stack trace would be a good start.
If you can do enough manual bisection (git or semi-random 
deletion of potions of code) to post the code that would also be 
good.

You haven't specified the DMD version you are using. Your LDC is 
'outdated', so make sure to first check whether it still fails

 Is this the entire stack trace? If dmd is also affected 
 chances it is a frontend bug.

 Well, on MacOs - yes. On a Linux, it is longer:

 [snip]

That is a very long stacks trace and combined with the very short 
stack trace on OSX, this is probably a stack overflow.
1) Do you have any very deeply nested types/templates somewhere 
or somehow created a cyclic dependency in semantic analysis?
2) Can you try with a bigger stack (ulimit -s)? If it still fails 
then its probably 1.

I assumed this at the beginning too...
The structures are not very deep, say 3-4 levels. But yes, I do 
have something like a loop you mentioned.
I'm trying to get rid of this right now. I hoped, if the compiler 
has problems with my construct, it would help me to find a better 
start place for this...

However, if I take your description: Is there a general way, to 
solve a cyclic dependency during the semantic analysis step? I 
mean, I'm trying to lowering logic in my code somehow, but the 
loop I need won't go away per se...

I can't really know without seeing the code, but if you can move 
the body of the loop into its own template that might work.

You're most likely hitting an ICE in the front-end (as both 
compilers crash). What you can always do is invoke the compiler 
in a GDB session. That's especially useful with an LDC CI build 
(download: 
https://github.com/ldc-developers/ldc/releases/tag/CI), as it 
features debuginfos and enabled LLVM/LDC assertions.

Please file an issue once you narrowed it down a little, ideally 
with a small reproducible test case.

Sorry, scrach that (it used to for the Windows CI build but 
doesn't anymore).

Ok... the longest part was: how to get the compilation string 
from dub :)

so, got the equivalent to
dub build
(with dmd)
started with gdb under Ubuntu and received after 10-20 seconds:

Program received signal SIGSEGV, Segmentation fault.

I'm not sure, how to shorten my code at this moment... So, if the 
traces don't help, let me know, I would spend some more time on 
this...
