xsltc triggers segfault in jit
------------------------------

                 Key: HARMONY-3547
                 URL: https://issues.apache.org/jira/browse/HARMONY-3547
             Project: Harmony
          Issue Type: Bug
         Environment: linux, x86_64 both "latest" of Apr 1 and svn head built here.
            Reporter: Santiago Gala


Running eclipse-3.2, all goes well, until it tries to index the documentation. Then I get,
after a while, the following dump:

SIGSEGV in VM code.

As seen in slot 50, xsltc is generating code for a XSL transformation, and giving it to the
interpreter. The crash happens after Jitrino tries to load a class in the bootstrap loader.
