2013年8月30日 · Right now I've been using GDB to disassemble a binary file and check out different registers and whatnot. Is there an easy command to examine everything on the stack? Can this be limited to everyth...

2021年5月3日 · When debugging with several threads, it is also useful to switch to a particular thread number and get the backtrace for that thread only. From the GNU GDB threads documentation For debugging purposes, GDB associates its own thread number--a small integer assigned in thread-creation order--with each thread in your program. Usage: info threads Then identify the thread that you want to look at ...

2020年2月6日 · What does ?? in gdb backtrace mean It means that GDB has no idea to which code the addresses in backtrace: 0x04004fc, 0x0400500, etc. correspond. and how to get the actual stack frames? That depends on why this is happening. There are two common scenarios: You are debugging the wrong executable.

2014年5月20日 · I'm working on a project with a friend but we have a problem because our application crashes. I ran it in gdb and got this after using the command bt full. What does this mean? Program received si...

2011年2月25日 · To load the corefile use gdb binary path of corefile This will load the corefile. Then you can get the information using the bt command. For a detailed backtrace use bt full. To print the variables, use print variable-name or p variable-name To get any help on GDB, use the help option or use apropos search-topic

2010年11月27日 · @Frédéric Hamidi: bt full gives you local variables, function arguments, etc. too but he wanted to get more frames than what gdb shows usualy.

2011年4月16日 · The program fails when the stack is 700 calls deep. I want to jump to the frame in which the function was initially called. However, gdb shows me the stack trace from the top of the stack about 20 entries at a time, and I wonder if I can somehow skip straight to the calling function without looking through the stack trace to find its number.

2013年1月14日 · For starters, you should be using something like std::vector that would throw an easily visible exception (and otherwise save you from managing the memory) when going out of bounds (if you use at()). Secondly, you should be able to set up a variable watch on x and y to see how they change, and look for when they become invalid, if that truly is the case.

2018年11月24日 · gdb bt Surely that is not the command you actually executed. Most likely you did something like this:

2016年9月10日 · where and bt are exact synonyms and produce exact same output. From the manual: The names where and info stack (abbreviated info s) are additional aliases for backtrace. info frame is totally different: it describes current frame, not the call stack. I don't really see the necessity of 'where' command It's there to make life easier for people who first used another debugger (e.g. dbx).
