I've found a discussion about the problem 6 years ago - http://article.gmane.org/gmane.comp.programming.garbage-collection.boehmgc/865/
Also, I've tried several ancient GC v6.x releases setting PROC_VFB - same failure.
So, I've set PROC_VDB enabled only for Solaris/x86 2.8 and 2.9.
Some other dated posts on the subject:

2. Boehm-GC 7.0 alpha 6 on Solaris 10/x86 and amd64 - http://article.gmane.org/gmane.comp.programming.garbage-collection.boehmgc/1329
