Stack trace for C++ using gcc
- by dimba
We use stack traces in proprietary assert like macro to catch developer mistakes - when error is caught, stack trace is printed.
I find gcc's pair backtrace()/backtrace_symbols() methods insufficient:
Names are mangled
No line information
1st problem can be resolved by abi::__cxa_demangle.
However 2nd problem s more tough. I found replacement for backtrace_symbols().
This is better than gcc's backtrace_symbols(), since it can retrieve line numbers (if compiled with -g) and you don't need to compile with -rdynamic.
Hoverer the code is GNU licenced, so IMHO I can't use it in commercial code.
Any proposals?
