I'm using QEMU 0.8.0 CVS under Windows. In the x86 version, one of my DOS application freezes QEMU amd I have to close it. I enabled the debugging with "-d in_asm,op_opt". At the end of the log file, I have over 1770 times the entry stating that QEMU is serving Int 0x08. Is this because the DOS application is poorly written or could this be a problem of QEMU ? What debug options are the best to use in my case ? Thanks for your opinions.
