Okay, I managed a minimal test case now:


import core.thread;

void main()
{
    new Fiber({ throw new Exception("fly"); }).call();
}

I want to add that I am quite annoyed that a bug like this makes it into a release. This cost me at least 2 days of production time.

I forgot: You need to compile with    -gx

Stack stomping (-gx) is a weird (and complex) feature and apparently wasn't
fully tested in combination w/ the new dwarf EH.
Note that you shouldn't run any production code w/ -gx.

Quick debugging of this program
---
void main()
{
    try
    {
    bar();
    }
    catch (Exception e)
    {
    }
}

void bar()
{
    throw new Exception("msg");
}
---
reveals that CallSiteRange for bar() is too small (66 instead of 70) and
therefor scanLSDA fails.
