bug#48189: ginstall: memory leak when omitting a directory

[Paul Eggert]

That one's not a real bug. 'install' is exiting, rather than calling 
'free' a couple of times just before exiting; calling 'free' would 
simply chew up runtime resources for no reason other than to pacify 
AddressSanitizer. So I'll close this particular bug report.

Most memory leaks found by AddressSanitizer in coreutils are false 
alarms. That being said, if you find one that isn't a false alarm we'd 
be interested in hearing about it. Stack overflows are also good to 
report too, except for tricky user-specified regular expressions (which 
require exponential resources in the worst case, no matter what the 
implementation is).
