Cannot Find Bounds Of Current Function In Gdb

When the stack is in a proper state, it contains a return address to the calling function and, somewhere above that, a return address to a higher-level calling function, and so If not, I'd really recommend you use qRcmd instead; then the GDB command is just "monitor", e.g. "monitor show sstepbits". Unable to step, next, print or to get any information.. Thanks, Jason.

It allows me to set and stop on appropriate breakpoint, but as soon as I try to single-step onwards, gdb reports the error "Cannot find bounds of current function" and the Gdb Layout Asm Thanks.... If instead you tried: (gdb) target extended-remote 192.168.0.10:1234 Remote debugging using 192.168.0.10:1234 0x400009c0 in ?? () (gdb) break main Breakpoint 1 at 0x8048338: file main.c, line 8. (gdb) c Breakpoint 1, However, I can't "step" or "next" through my code, nor can GDB apparently determine which line of code is the current line.

Type "show warranty" for details. check my blog How does it explain the message “Cannot find bound of current function”, which is apparently a message from the debugger? –Eric Postpischil Feb 6 '14 at 18:51 add a comment| up Well, the credits certainly goes to Jason....
