[Qemu-devel] Debugging

[Tom Musgrove]

Hi,

I have some questions on debugging - here is exactly what I'm doing, might 
be of use to other newbies with gdb

# cd qemu
# gdb i386-softmmu/qemu
# break main
# run  /Users/tom/Desktop/linux.img -d
# step

okay, I keep stepping

I get to line 981 setvbuf(logfile,NULL, _IOLBF, 0);

Then after the next step, it prints out tlb_flush:

with a ton of apparently memorry addresses and such (I'll include as 
attachments runs from both freedos.img and linux.img).

then finally it prints

Program received signal EXC_BAD_ACCESS, Could not access memory.
0x00020b28 in cpu_x86_exec (env1=0x1f) at 
/Users/tom/darwine/related/qemu/exec-all.h:284
284         if (!tb->jmp_next[n]) {

any further attempts to step repeat the above message

This is off of the Darwin porting branch set up by Pierre.

Tom M.
