Subject: [PATCH] ccpp: tell gdb to analyze saved binary image
|
|
|
|
This is particularly useful when dealing with crashes in containers and
|
|
changed root environments. GDB reads the debug information from the
|
|
source elf and if the source elf is not available GDB generates useless
|
|
backtraces.
