digitalmars.D.learn - m32mscoff with lld-link causes SEH errors

Hi, I have a simple program with just one line (below).  I've 
compiled on Windows using
dmd -ms32coff app.d
and have had LINKCMD set to lld-link, but get the following 
errors. Is lld-link only for 64-bit compiles (-m64 is the only 
one that gives no errors)

Nope, but SafeSEH is a 32-bit-only feature. DMD doesn't emit 
SafeSEH compatible object files, and LLD seems to have a 
different default setting in that regard compared to MS link.exe. 
Using `-L/safeseh:no` should work around this.

Thank you!  One more thing to add to my compile/link notes =)

It successfully made the executable, and it runs fine - until 
exit lol.  Must be more tweaks needed.

Edit source/app.d to start your project.
