Re: [perl #48677] [BUG] r23917 led to 'make' failure

Hi,

Basically, it appears to me that the failure happens with some versions 
of GCC when you're doing (once you look through the macros):

*d = *s;

Where d and s are PMCs. I can only conclude that the compiler is 
generating all the reads, then all the writes, which of course requires 
sizeof(PMC)/sizeof(void*) registers to do the copy, and then finding it 
can't allocate it when doing the cgoto core, possibly because when 
compiling computed goto it backs out of doing other things it does with 
other runcores that can resolve this issue.

I suspect re-writing it to do a memcpy would solve the problem...anyway, 
sleep calls...
