How can I interpret a .stackdump file?

Question

this question is likely a repeat of Using a stackdump from Cygwin executable - but I'm a beginner, and I didn't understand the answers, or even parts of the question.

I'm pretty new to c++ and programming and I'm developing in NetBeans. I'm working on some code that compiles just fine, but fails while running. If I use the debugger I get the following error:

1 [main] all 6200 exception::handle: Exception: STATUS_ACCESS_VIOLATION
881 [main] all 6200 open_stackdumpfile: Dumping stack trace to all.exe.stackdump

I've managed to find the file all.exe.stackdump, and I can read it via notepad++, but I don't understand what it means. I gather by the other question that there's a user friendly way to decode this file, but my best guess bash$ gdb all.exe.stackdump was ineffective. What's the best way for me to use this file in debugging?

Just in case it's helpful, here's the contents of all.exe.stackdump

Exception: STATUS_ACCESS_VIOLATION at eip=00434C41

Answer 1

You can use the "Function" addresses as arguments to addr2line.

addr2line -f -C -e main.exe 0xADD4355

Filter it using awk and pipe in all addresses:

awk '/^[0-9]/{print $2}' main.exe.stackdump | addr2line -f -C -e main.exe

If you see ??'s instead of function names, you'll need to rebuild with debug symbols (-g, -ggdb3, ...)

Answer 2

This is a common problem for many guys; and usually they will tell you use gdb. However this is not always a reasonable answer. You mustn't re-compile it, since it isn't guaranteed the new build has same symbol addresses as the crashed one. There are several tools that could be helpful: objdump, addr2line, etc. You can do "objdump -D -S build.out > build.rasm.txt", and then search those functions addresses among the text. Addr2line is also a good choice for identify those functions. If you are going to handle such crash problems often, it's suggested writing a script tool to help your work.

Good luck.
