Samba sometimes does not dump core on a SIGSEGV etc

[Richard Sharpe]

Hi folks,

When I was working on the Ceph VFS I noticed that Samba would not dump
core in the VFS when I caused a SIGSEGV.

In looking at this same problem elsewhere, it seems that this might be
because in the VFS Samba has done a setreuid to the mapped user, and
the Linux kernel will not allow a core dump under those circumstances.

Should the Samba SIGSEGV handler return to root before trying to dump core?
