Hi,

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:
1. Solaris (PROC_VDB) and fork - http://article.gmane.org/gmane.comp.programming.garbage-collection.boehmgc/1023
2. Boehm-GC 7.0 alpha 6 on Solaris 10/x86 and amd64 - http://article.gmane.org/gmane.comp.programming.garbage-collection.boehmgc/1329

Regards.
