Noticed an issue the other day when branching instructions follow each other, such as in a GetPC procedure like

jmp post_get_pc
get_pc:
pop EAX
jmp over_post_get_pc
post_get_pc:
call get_pc
over_post_get_pc:

then jmp over_post_get_pc do not get the offset right. A quick dirty fix is to place a dummy NOP in between consequential branches, like:

jmp post_get_pc
get_pc:
pop EAX
jmp over_post_get_pc
nop
post_get_pc:
call get_pc
over_post_get_pc:

It's probably a bug with my algorithm that notes the indexes of those branches and attempts to calculate the offset for each instruction line by line. I just don't think I have time to fix this ATM.
