Something must have gone really wrong to get this error. Most 
likely, the CPU instruction pointer ended up in a memory area 
without any code in it.

Windows exception handling is tricky (see Don/Walter's recent 
discussion), but basic cases should be well-covered by the 
compiler/runtime test suite.

So, I suspect one of the following happened:

- Your program is exhibiting an edge case and uncovering a bug 
not covered by the test case. If this is the case, please reduce 
your program to a minimal, self-contained example, and file a bug 
report.

- There is a bug in your program that is causing its memory to be 
corrupted. Using @safe can help narrow it down 
(https://dlang.org/spec/memory-safe-d.html).

- There is something specific to your machine that causes the 
problem to occur there, but not on the test runners. This could 
happen e.g. due to software which alter behavior of other 
programs (like through DLL injection), or using a specific 
Windows version. You can eliminate this possibility by running 
the DMD test suite.
