Samba 2.2.0 smbpasswd segv

[Rob Mason]

Further information:
It appears to be the addition of --with-spinloocks in the configure that causes
the problem.
Platform is Linux (RH6.2), ran on kernels 2.2.14, 2.2.19 and 2.4.3
gcc ver is 2.95.2

When I build 2.2.0 with the following configuration:
/configure --target=i586 --with-pam --with-vfs --with-spinlocks
--with-acl-support
--with-quotas --with-msdfs --with-configdir=/RamDisk
I consistently get a segmentation fault from a call to smbpasswd -j DOMAIN.

When I rebuild with a simplified config:
./configure --target=i586 --with-quotas --with-configdir=/RamDisk
all is fine

Below is debug 10 output and stack trace.
If I get time this afternoon, I'll try to re-add the config options one by one
to see where problem occurs.

Debug 10 output:
