--- Comment #5 from Luis Machado <luis.machado at linaro dot org> ---
While investigating this, I noticed something else that may indicate a
kernel-side counterpart.

Although this doesn't FAIL for x86_64-linux/Ubuntu 20.04, I can trigger FAI=
L's
manually if I produce enough noise (by, for example, enabling infrun debugg=
ing)
while the testcase is running.

So it seems that this test passes if GDB runs the test undisturbed (and
quickly). If there is considerable noise going on during GDB's execution of=
 the
test, we will run into the SIG32.

It is almost as if the kernel misses sending the signal notification for SI=
G32
in some cases. Adhemerval, a glibc maintainer, mentioned there might be a r=
ace
going on somewhere.
