qemu-1.5.0 gdb not working
In mac OSX, compile by :./configure --cc=/opt/local/bin/gcc-mp-4.8 --enable-cocoa --target-list=x86_64-softmmu --audio-drv-list=coreaudio --prefix=/Users/peter/qemu --enable-debug --disable-werror --extra-cflags=-O2 --enable-vnc 
start qemu by:~/qemu/bin/qemu-system-x86_64 -hda hd10meg.img -gdb tcp::1234 -k en-us -S -m 256m
i start gdb and insert two breakpoints at 0x7c00 and 0x7c01, after "c", it hit 0x7c00. Then i "c" again, it stay in 0x7c00, but it should execute 0x7c01.
