My older cross-compiler didn't complained, so it went unnoticed for me until now and the faulty code was added during the 4.19 merge window. It can be pulled from my git tree as well: git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux.git parisc-4.19-3 Fix an unitialized variable usage in the parisc unwind code.

Fix it.
