Re: [rvm-research] Running RVM fails in Mavericks

The problem seems to be before a thread terminates because it seems to instantly die when bootThread() is called.
When just running rvm I get the following error message:

JikesRVM: TROUBLE.  Got a signal (Segmentation fault: 11; #11) from outside the VM's address space in thread 0xa08d81a8.

JikesRVM: internal error
invalid native thread address (not an address 40000)
Abort trap: 6

I tried to print the ip, tr and sp right before bootThread() is being called and got the following output:
Booting thread: [ip:3307726436034664,tr:17004330900fc,sp:200000370]

So as we can see, the native thread magically transformed from 17004330900fc before bootTrhead() to 40000 in the signal handler.
Am I using the wrong compiler? Am I supposed to use Apple's clang rather than the GNU gcc4.7?

Or maybe the asm __x86_64__ asm code needs fixing? Or maybe I'm doing something wrong...
