Bug #2417: i386-only failure involving nmalloc (ZALLOC_SLAB_MAGIC assert)

Author: John Marino
Status: New
Priority: Normal
Target version: 

The yamcha tools build on both platforms.  However, they only work on x86_64.
When the yamcha tool pkemine tries to generate a file for cabocha on i386, it core dumps:

#0  _slabfree (ptr=<optimized out>, flags=<optimized out>, rbigp=0x0)
    at /usr/src/lib/libc/../libc/stdlib/nmalloc.c:1165
1165            MASSERT(z->z_Magic == ZALLOC_SLAB_MAGIC);

The 4-frame backtrace is here: 

The i386 pkemine executable is here: 

A packed coredump is here:

The two platforms have different malloc implementations.  Why is i386's implementation dumping why x86_64's is happy?
