Defining _XPAGE for sfr at 0x92 seems to fix the global initialization problem. I'm not entirely sure the problem is gone, but it at least fixes my simple test case. For my program to work, I still have to use --xram-loc of somewhere around 896 to 1024 bytes (0x0400 works) Can anyone shed some light as to why the default xram location doesn't work?
