Modified files:
gnu/usr.bin/tar diffarch.c
Log:
Quick fix for attempts to free non-malloc()ed memory. The variables
current_file_name and current_link_name sometimes point into the
middle of malloc()ed memory and sometimes point to alloca()ed memory,
but free() is sometimes called on them. This seems to be harmless
for the usual tar operations, but it is usually fatal for `tar -W'.
E.g., for `cd /etc; tar Wcf /tmp/foo rc', at the start of
verify_volume(), current_file_name points to alloca()ed memory, and
tar attempts to free it.
