GCJ + Roguewave Threads?

["Prabhakar, Vijay (IT)" <Vijay dot Prabhakar at morganstanley dot com>]

Has anyone had experience or gotten GCJ to work with Roguewave threads?  I'm trying to get a set of Roguewave threads to attach to the VM via the JvAttachCurrentThread() method and the program seems to crash in the boehm-gc.  Alternatively, I've tried to create the VM while in the thread and then attach it, and it crashes in gc_push_all_eager in mark.c, near line 1349.  I'm using gcc 3.2.3-42.  

On a side note, would it be possible to upgrade some/all of the gcj related files without changing the actual gcc compiler?  I can't really change the firm to gcc 3.4.3, but if I could upgrade to a more recent GCJ and maintain interoperability, that would be great.  Thanks!

Here's a clip of the portion of the code:
 
 
if (top == 0) return;
/* check all pointers in range and put in push if they appear */
/* to be valid. */
lim = t - 1 /* longword */;
for (p = b; p <= lim; p = (word *)(((char *)p) + ALIGNMENT)) {
q = *p;  // <---crashes here
GC_PUSH_ONE_STACK(q, p);
}


here's a stack trace:
