I've spent some more time digging into this and found a simple way to reproduce it. The problem only seems to occur when a probe is located in a static function. Some comments in dt_link.c indicate that there's some special handling that's needed in this case, but I still don't quite understand what's causing the problem. I've placed a simple provider definition and sample program that reproduce the issue here: http://people.freebsd.org/~markj/dtrace/bin167103/ When the repro program is built, dtrace(1) will segfault when processing the object file. When the patch attached to the PR is applied, dtrace will just exit with a generic error: dtrace -G -s provider.d repro.o provider: failed to link script provider: an error was encountered while processing repro.o *** [beforelinking] Error code 1 I'm still working on figuring this out.
