what's wrong gdb in suse 8.2

zhangxudong

when I set breakpoint and run, gdb error as following:
   Cannot insert breakpoint -2.
   Error accessing memory address 0x4000bb50: Input/output error.
   The same program may be running in another process.
why?

You have another copy of your program running in your Linux.
Or you didn't compile your program with -g option.
Or you set the breakpoint at a wrong place.

thanks!

Because you link a share library, and one of your share library may be currently used by another program. So gdb will report you that "The same program may be running in another process."
