Well, I'm in the build tree's src subdirectory and xsymbol is defined,
so I'm not sure where else it could be coming from! It's not like I have
multiple .gdbinits lying around that define xsymbol :) I tried sourcing
./.gdbinit explicitly: it changes nothing.

But unfortunately my attempt to reproduce this bug with the same message
have failed so far (it must be dependent on something else in Emacs
state, probably something transient), and the coredump is naturally not
compatible with an Emacs built without optimization. So this probably
needs to be closed as unreproducible :(
