Can I set the breakpoint/watchpoint/smth else in gdb for register value?
I want to break when $eax will have value 0x0000ffaa.
Is it possible with gdb or dbx or any other unix debugger?

I compiled GDB 7 on a Mac OS X Leopard system. When stepping through a C program, GDB fails to step through 'printf()' statements, which probably don't have associated debug information, and starts printing "Cannot find bounds of current function."
Here's some output:
$ /usr/local/bin/gdb try1
