Best guide or video for gdb <register level debugging>
would like to know best guide or document for gdb for different architectures x86 , power pc etc..
would like to understand how to debug segmentation faults because of stack corruption ..
understand utilities ELF , objdump etc..
please guide me
You debug "stack faults" by seeing what's happening before the fault. It's difficult to make sense of the stack fault itself, for the same reason a museum is more useful before it burns down.
Register information isn't too useful without knowing what's in those registers. That's why gdb likes to have debugging information -- to tell it how to get variables, not just random cryptic registers.
An example using gdb debugging a crash fault:
Debugging a crash without finding the context around it isn't too useful, you have to see what happens BEFORE the crash.

My queries are as follows:
Can a 32bit gdb (v7.6) and ddd (data display debugger - v3.3.12), debug a 64bit executable ?
If I have a small 64bit a.exe executable that seems to work.
If I have a more complicated executable... (4 Replies)

But when I debug in gdb I see the the code changes in soucre file. But the break point does not hit at that place as if it did not... (1 Reply)

I'm trying to use the GDB debugger and DDD to debug 64bit code. It seems that the AIX toolkit gdb version 6.0 works with 64bit code. But the ddd tool when running gdb gives the following errors :

warning: "": not in executable format: There is an input... (2 Replies)
