The last message I had for the crash below is:

I just have been told it's still happening with the gdb 8.3 testsuite on the
Gentoo test machine:

Linux hake 4.19.52-gentoo #2 Tue Jun 18 13:51:01 EDT 2019 parisc PA8600
(PCX-W +) 9000/785/C3600 GNU/Linux

This seems to be a minimal reproducer:
https://481768.bugs.gentoo.org/attachment.cgi?id=361728

It doesn't crash for me on debian (other kernel, other userspace, older gdb).
But there is something fishy anyway.
It seems the "set tp = {0,0}" doesn't work as expected.
gdb prints the set zero-values correctly, but it doesn't seem to be stored correctly to memory.
"set tp.a = 10" does work though.
