What steps will reproduce the problem?

When invoking xar_close in one case, it results in a crash in libz:

Exception Type:  EXC_BAD_ACCESS (SIGSEGV)
Exception Codes: KERN_INVALID_ADDRESS at 0x0000000104a00000

I still need to investigate this further as this is the first time I see this 
in 3 years.

What is the expected output?

A xar file

 What do you see instead?

A crash

What version of the product are you using? On what operating system?

1.5.2 Mac OS X 10.6.8

As far as I can tell, this is related to not having enough free space on the 
disk.

IMHO, xar_close should not crash but returns an error.
