[linux-lvm] lvcreate seg faults in 1.0.1-r4

I am having trouble getting lvcreate to work.  I've been able to create the PV and VG, but lvcreate always core dumps with a seg fault.   I've confirmed that I have the same code level in the kernel and tools (1.0.1-rc4).  I've tried compiling the tools with gcc (v2.96) and egcs (v2.91.66), but both fail.  I'm running a 2.4.14 kernel, lvm as a module, and glibc-2.2.4-19.  
  The problem seems to be with a corrupt lvol name from what I see in the gdb output I've attached.

 Any help would be great.
