A branch instruction in thumb mode might either be narrow or

armasm seems to have a bug when calculating the difference
between two symbols, where there's such a branch inbetween.
If the branch immediately seems to require a wide instruction,
the symbol difference is calculated properly, but if the
branch is made wide as a consequence from another branch
being made wide, the symbol difference isn't calculated
properly.
