[Libunwind-devel] mincore_validate fails sometimes

[Daniel Vassdal]

We have an issue where on Yocto Morty 2.2 mincore_validate() sometimes 
unexpectedly returns -1.
This seems to happen most often directly after the system has been booted.

The check that fails is
> if (!(mvec[i] & 1)) return -1;

The reason I suspect this is a libunwind problem is that when HAVE_MINCORE 
isn't defined, it works well.
This workaround is sufficient for us, but in case this indeed is a bug I 
figured I'd let you guys know.

Best regards,
