Hi people,
I've noticed smtpd's deliver_maildir getting killed on syscall 15
(chmod) with the latest snapshot. I've rebuilt and core dumped it as
described by Sebastien and this is the backtrace I got:
#0 0x00001d7e8175149a in chmod () at <stdin>:2
#1 0x00001d7c72744ffe in mkdirs (path=0x7f7ffffdd0d0 "/home/gbe/Maildir",

smtpd's output looks like this when this happens:
[... noise omitted ...]
delivery: TempFail for 361bd1ee4342b3f8: from=<g...@charm.unobtanium.de>,
to=<r...@unobtanium.de>, user=gbe, method=maildir, delay=0s, stat=Error
(terminated; signal 6)
debug: mda: session 757ea75d406dfe65 done
[... noise omitted ...]
(this is with "abort" added to all pledges)
The weird thing is that as far as I can see the process handling the
delivery seems to correctly pledge wpath. If I remove the pledge from
smtpd.c, line 693, everything works fine.
Any hints on how to debug this further? I can provide core files if
needed.
