Nope. The bug is in your program (but I'll grant you -- it's an
obscure one).

Compile your code with -Wall, and you'll see this:

$ gcc -Wall junk3.c
junk3.c: In function 'main':
junk3.c:19: warning: implicit declaration of function 'getline'
junk3.c:7: warning: unused variable 'count'

The 'man getline' tells you to do this:
       #define _GNU_SOURCE

Adding that to junk3.c, and compiling again with -Wall, tells you
the root of the problem:

junk3.c: In function 'main':
junk3.c:20: warning: passing argument 2 of 'getline' from incompatible pointer 
type

Fixing that problem:

      // int lineSize, count; 
      size_t lineSize;

cures the warning, cures your bug, and makes valgrind happy:

==28863== ERROR SUMMARY: 0 errors from 0 contexts (suppressed: 4 from 1)
