I guess not, when I remember correctly this has already been repaired
for armv6m. The problem for me is that .Lj9 is defined as a negative
number. As a consequence r13 points to nirvana and
str r0,[r13, #8] creates an Exception.
# [87] begin
push {r4,r14}
ldr r4,.Lj9
add r13,r13,r4
# Var bit located at r13+0
# Var direction located at r13+4
# Var $self located at r13+8
str r0,[r13, #8]
strb r1,[r13]
str r2,[r13, #4]
.Ll2:
.....
.Lj9:
.long -32840
.Lj7:
.long 32768
.Lj10:
.long 32840

Thanks a lot, Michael!
