I'm told that this commit is the cause of the current PowerPC 603 (all flavors) and MPC8240 issue causing all machines using those CPU's to crash immediately to prompt. Specifically, Line 185 in src/emu/divtlb.cpp :

   m_refcnt[m_live[liveindex] - 1]--;

Should be in the if on top of it, and maybe more. That line is bad because it's outside of the m_live[liveindex] != 0 test (which means there's no tlb entry there yet)

An easy example set to test would be gcus
