Furthermore, GDB needs to use kernel interfaces which have properties that are awkward for certain threading use cases, such as having to conduct operations from specific threads. But if you only want to look at coredumps, that won't matter (in theory, GDB is of course still structured around such interfaces to some extent).

There is LLDB, but some time ago, I found it curiously non-aligned with typical Linux userspace usage scenarios. It may matter less for kernel crash dumps. There's also the possibility to read the ELF data structures directly. It's harder for DWARF.
