what cpu/machine settings are you using  ? It could be a prefetch issue where Hatari didn't correctly update the prefetch words.
I have attached my cfg file and the offending binary. From my experiments I can see that the problem occurs when:
- "Cycle exact, slower" isn't set
- "MMU emulation" is set

So it has two different test cases. Can you reproduce them?
What is the content of the registers ('r') when reaching the breakpoint ?
The PC and disassembly at the PC looks good:

Prefetch 00032058 123c0001 (1) 0099 (1) 123c (1) 0001 (1)
00032054 103c 0099                MOVE.B #$99,D0
Next PC: 00032058

So whatever is happening it's happening after I step to next instruction.
