Re: [Crash-utility] right shift of the subtraction result

----- Original Message ----- No, it is a crash bug. If you turn on the console mode, you can see the string that is passed on to gdb. Simple example: crash> !tty /dev/pts/8 crash> set console /dev/pts/8 debug console [2850]: /dev/pts/8 console: /dev/pts/8 crash> set debug 1 debug: 1 crash> The simple shift case works, and you can see the string that gets passed to gdb on the 2nd line of output, in the bracket after gdb_pass_through: crash> pd (15 >> 1) error() trace: 467e99 => 51c147 => 518ca6 => 46eaff gdb_pass_through: [p (15 >> 1)] p: per_cpu_symbol_search((15 >> 1)): NULL $9 = 7 crash> But by adding the internal set of parentheses, the string gets clipped, and just "p ((15+1)" gets passed to gdb: crash> pd ((15+1) >> 1) error() trace: 467e99 => 51c147 => 518ca6 => 46eaff p: per_cpu_symbol_search(((15+1)): NULL gdb_pass_through: [p ((15+1)] error() trace: 467e99 => 51c1e7 => 51a7d5 => 46eaff p: gdb request failed: p ((15+1) crash> So it's either related to the crash command line redirection code, or in the process_gdb_output() function. (Feel free to debug it if you have the time...) Thanks, Dave
