Of course, all programs compiled without '-pg' work fine for me.
I found this issue when I profile my application with gprof(1).
For example, following example C source code fails to execute on OpenBSD 7.0.
Profile is partly broken and has been for a while.
Compiling with -static and removing any pledge() call allow profiling to work.
Yes, and the proposed patch effectively enables -static if -pg is used.
I don't know if this the best fix. But this issue keeps popping up and
it would be nice to have something that works out of the box.
I would not mind this patch going in.
Yes.
When I use ld.bfd as /usr/bin/ld, this problem doesn't happen
although without '-static' option. So, my patch is helpful to keep same
usability between ld.bfd and ld.lld.
Pledge and unveil interfering with profiling is a separate issue which
is more obvious when it occurs and can easily be worked around by the
developer.
I don't have pledge issues in my use case.
My patch isn't intended to change anything about pledge.
