Fix for an integer overflow bug that could cause a segfault on certain
pathological archives.

(Unlikely to have security implications, the only way to trigger it basically
wound up doing memset(dbuf,x,2^31) and triggering an immediate segfault.  The
test basically gives us a more polite error message.)

Thanks to Ned Ludd and the Gentoo security guys for finding this.
