No it always segfault in the third attempt.
a) create tags files
b) switch to a different branch/version (in other words change some c files )
c) run gtags -c -i -f gtags.file . it will throw an error primary key size = 0
d) run gtags -c -i -f gtags.file it will segfault

With the linux kernel source i guess it should be easy to reproduce.
