GDB: Listing all mapped memory regions for a crashed process

Question

I\'ve got a full-heap core dump from a dead process on an x86 Linux machine (kernel 2.6.35-22 if it matters), which I\'m attempting to debug in GDB.

Is there a GDB

Answer 1

The problem with maintenance info sections is that command tries to extract information from the section header of the binary. It does not work if the binary is tripped (e.g by sstrip) or it gives wrong information when the loader may change the memory permission after loading (e.g. the case of RELRO).
