Question

I’m using Linux redhat 3, can someone explain how is that possible that i am able to analyze
with gdb , a core dump generated in Linux redhat 5 ?

not that i complaint 🙂 but i need to be sure this will always work… ?

EDIT: the shared libraries are the same version, so no worries about that, they are placed in a shaerd storage so it can be accessed from both linux 5 and linux 3.

thanks.

In my experience analysing core file, generated on other system, do not work, because standard library (and other libraries your program probably use) typically will be different, so addresses of the functions are different, so you cannot even get a sensible backtrace.

Don’t do it, because even if it works sometimes, you cannot rely on it.
