Re: bochs on sparc/solaris

Hi,

This sounds like a problem for me ...

Could you help with more info from gdb ?

While running fetchDecode32, could you print the parameters to the function
? Is there a NULL pointer or illegal memory location ?
Also some CPU members: EIP (see macro in cpu.h for details), icount,
pAddrFetchPage, eipFetchPtr.

Thanks,
Stanislav

One more thing.. Here is the stack backtrace. I did not compile with
debugging info.

Core was generated by `/opt/tmp/bochs-20121214/bochs -f bochsrc'.
