How to inspect std::string in GDB with no source code?(如何在没有源代码的情况下检查 GDB 中的 std::string?)
问题描述
I'm trying to debug a program that has no source code available, and I need to look at what it has stored in a std::string. I've been Googling and looking on here, and I've found some information about outputting STL containers, but all of it refers to variables, with no source or debug information all I have is a memory offset of the class data. Is there any way to do this?
Every std::string
implementation has a pointer to the raw characters in it somewhere. For g++ 4.x
, that pointer is at offset 0
into the string.
If you know that the string resides at e.g. 0x7fffffffda88
, then
print *(char**)0x7fffffffda88
is what you need.
