Backtraces were corrupted on some kernel versions as the VDSO memory area being
used for the return from the kernel had unset permissions (--- instead of r-x).
It affected the GDB gcore command and IIRC Frysk also respected these broken
permissions and failed in such cases.
The kernel Bug has been tracked at least by:
