Okay. We need to determine which function is failing. Could you do something
like this:
#define zcur __attribute__((zero_call_used_regs("used-gpr")))
and then add `zcur` to each function, while compiling the module with
`-fzero-call-used-regs=skip`. Then remove the `zcur` attribute from functions
until it works? I know it's a PITA, but otherwise I'm just guessing at which
function's causing the failure...
