Sadly not.  The debug symbols need to be specific to the exact binary
you booted.

Any change in the compilation will result in the translation being
useless.  What addr2line is doing is saying "which specific bit of
source code did the compiler/linker end up putting at $X".

I wouldn't worry too much - I expect (the lack of) the aforementioned
changeset is the cause of your issues.
