That is expected: the --enable-block-signals=no makes it unsafe to call
into libunwind without some other means of protection against recursive
entry back into libunwind from a signal handler.
It may be a good idea to add such protection to do_backtrace in
test-async-sig.c, both to make this test pass, and to demonstrate what
is required when --enable-block-signals=no
Unfortunately, I see no way to add such protection conditionally (depending
on whether --enable-block-signals is on or off). Is there a way?
Thanks,
