freebsd stable - Jan 2017 - Strange dtrace warning on running svn, perl and other programs on stable/10 r310494

I keep getting these warnings whenever I run svn, perl, and other 
programs.

WARNING: number of probes fixed does not match the number of defined probes (16
!= 18, respectively)
WARNING: some probes might not fire or your program might crash

They also clobber the building of security/vpnc. Some "clever" Perl 
script is being used to produce a .c file on stdout and a .h file on 
stderr while building vpnc.

Any chance of getting rid of the messages, or at least disabling them?

This is on stable/10, r310494.

/etc/make.conf contains:

STRIPCFLAGS+=-fno-omit-frame-pointer
WITH_CTF=1
WITH_SSP_PORTS=yes

This particular system will soon be upgraded to stable/11, r310770. 
Maybe my troubles will disappear once the transition is complete.

This is emitted by some code that registers userland DTrace probes
during process init. The mechanism used in stable/10 doesn't work in
some cases. This has been fixed in 11, but the change cannot easily be
merged back.

If you're not planning on using the DTrace probes, the message can be
suppressed by setting DTRACE_DOF_INIT_DISABLE in the environment.

Indeed, this message is gone on stable/11.

Upgrading to stable/11 and recompiling all installed ports made the 
warnings go away.

Happy New Year!
