Re: no "--opt:size" leads EXE to "SIGSEGV: Illegal storage access. (Attempt to read from nil?)"

Compile without -d:release and with `-d:useSysAssert -d:useGcAssert`, you have 
a memory corruption, most likely because of a bug in your wrapping code. Don't 
assume that it's "only" \--opt:size that makes your program crash, you are 
simply "lucky" for the other optimization levels.
