 > I see the code in os::Linux::capture_initial_stack() checks the 
__libc_stack_end symbol to try to discern where the initial stack 
section is for the VM. I have a case where an executable (over which I 
have no control) loads a shared library I've written, but does so in a 
"stack sandbox". My shared library creates a VM through a JNI call. The 
VM gets the stack section for the main program, but is running in this 
sandbox and a crash occurs pretty quickly. Specifically in the 
guarantee(get_thread() == thread) assertion.
 >
 > Are there any mechanisms for helping in this situation? From my 
reading of the code, my only option is to recompile the VM with a 
modified capture_initial_stack(), which is a little daunting (the 
recompile process -- not the code modification).
