dtrace crashes on ustack

[Steven Hartland]

When running dtrace looking at syscall::write:return for a java
app with a ustack call for the first few calls I get:-
              dtrace: ERROR: gelf_getehdr() failed: No error: 0

And then after a number dtrace crashes:-

#0  0x0000000800fcc59d in _malloc_prefork () from /lib/libc.so.7
[New Thread 80283c500 (LWP 100815/dtrace)]
[New Thread 8012041c0 (LWP 101294/initial thread)]
(gdb) bt
#0  0x0000000800fcc59d in _malloc_prefork () from /lib/libc.so.7

#3  0x0000000800658523 in pthread_getprio () from /lib/libthr.so.3
#4  0x0000000000000000 in ?? ()
Cannot access memory at address 0x7fffffbff000

Kernel is compiled with dtrace, world has been rebuild with
WITH_CTF=1 as has openjdk7 port.

Any ideas?

    Regards
