Ah!  In that case, you are building with -D_FORTIFY_SOURCE=2 (it is one
of many things enabled with that HARDENING flag).  If setting
DEB_BUILD_HARDENING_FORTIFY=0 makes the problem go away, then that's the
issue.

Given the advantages that fortify provides, I'd try to convince upstream
to rename that struct.  :)
