I think I've found the problem! and it could be related to a bug in Ruby:

In my SIP parser (Ruby C extension like Ragel HTTP parser) I generate
Ruby string encoded in UTF-8 using:

  rb_enc_str_new(s, len, rb_utf8_encoding());

But if I change it to:

  rb_str_new(s, len)

then the segment fault does NEVER occur!
