You need to add the offset when you are indexing through gl_pathv:

     ‘gl_pathc’
          The number of elements in the vector, excluding the initial
          null entries if the GLOB_DOOFFS flag is used (see gl_offs
          below).

I don't know why gl_offs even exists, it does not seem very useful.
(The caller cannot supply its own buffer via gl_pathv, and the prefix
is overwritten by null pointers.)

Thanks,
Florian
