Hello. I work on project, that works on ARMv7 (Raspberry PI 2). Some times I get error in random places (build to build in different place, no rebuild - stable error place):

Fatal error in EH code: _Unwind_RaiseException failed with reason code: 9 Aborted

I found few issues on github

https://github.com/ldc-developers/ldc/issues/2208
https://github.com/ldc-developers/ldc/issues/2058
https://github.com/ldc-developers/ldc/issues/2024

But I don't understand how workaround this.
My ldc2.conf have no special flags, I don't use optimization.

default:
{
    switches = [
        "-I/usr/include/d/ldc",
        "-I/usr/include/d",
        "-mtriple=arm-linux-gnueabihf",
        "-gcc=arm-linux-gnueabihf-gcc",
        "-L-L/home/deviator/workspace/arm-linux-gnueabihf",
        "-defaultlib=phobos2-ldc,druntime-ldc",
        "-debuglib=phobos2-ldc-debug,druntime-ldc-debug"
    ];
};

Trying add "-mattr=+strict-align" has no effect.
I see only one way for fix it: don't use exceptions. But it require a lot of work on rewriting existing code. May be this problem has more elegant solution?

What's the output of `ldc2 --version` ?

LDC - the LLVM D compiler (1.3.0):
  based on DMD v2.073.2 and LLVM 4.0.0
  built with LDC - the LLVM D compiler (1.3.0)
  Default target: x86_64-unknown-linux-gnu
  Host CPU: skylake

last ldc from fedora repo

Can you try https://github.com/ldc-developers/ldc/releases/tag/v1.4.0-beta1 ?

Cross-compilation should be easier if you use the newly added ldc-build-runtime tool. There's a wiki page describing how it can be used: https://wiki.dlang.org/Building_LDC_runtime_libraries

It sounds like you have some memory corruption somewhere, doubt the issue is in exceptions. Can you try running the stdlib tests and see if those all pass?  Easiest would be 1.4 beta with instructions Petar linked you to.

Yes, I try it now, but this error is difficult to catch and, I think, if issues don't closed and in change log no information about this error it can occur again.

How I can do this with minimal work?) I need to compile libs with -unittest flag and run empty file (void main(){}) on RPI?

I build phobos and druntime with -unittest flag and run on RPI `void main(){}`
and have this

./test
Not safe to migrate Fibers between Threads on your system. Consider setting version CheckFiberMigration for this system in thread.d

No more messages. I think all tests passed?

Looks like at least core.thread ran, better to use the test runner to make sure.  Just follow the instructions from that wiki page, there's even an example for Android.  Simply replace with your toolchain and flags.  You don't even need to build ldc, can use the ldc 1.4 beta release.

I know, I build phobos and druntime on host x86. Run test on RPI.
