Yeah; I think the gdb version is too old.

Adding the following patch turns this into an "unsupported" (on this host, =
at
least):

diff --git a/gcc/testsuite/jit.dg/jit.exp b/gcc/testsuite/jit.dg/jit.exp
index 3568dbb..8bf7e51 100644
--- a/gcc/testsuite/jit.dg/jit.exp

I'll try the combination of these patches on my regular x86_64 workstation.=
