The Linux specific backtrace()
and backtrace_symbols()
allows you to produce a call trace of the program. However, it only prints function addresse
The excellent Libbacktrace by Ian Lance Taylor solves this issue. It handles stack unwinding and supports both ordinary ELF symbols and DWARF debugging symbols.
Libbacktrace does not require exporting all symbols, which would be ugly, and ASLR does not break it.
Libbacktrace was originally part of the GCC distribution. Now, a standalone version can be found on Github:
