That causes an infinite loop, as you're skipping the k++ at the
bottom. I suggest changing it to a for loop.

Also, the third test should probably be testing voffset_next rather
than voffset_curr.

Even if I change the traps to set the variable to zero instead of
"continue"ing, I don't get faces.

Looking at the code, it only converts boundaries and areas to faces,
not lines, but the input (bldg_resid) only contains lines.

If I use v.edit to convert lines to boundaries, then add centroids
with v.centroids, I get faces after v.extrude.
