Stress testing of the AsyncGetCallTrace() interface has exposed an
intermittent assertion failure:

# assert(pc_desc != 0, "scopeDesc must exist")
# Error ID: src/share/vm/runtime/vframe.cpp, 524

During the stack walk, vframeStream finds a compiled frame for which it
cannot find a scope description. Here is a snippet of the stack trace:

  [6] report_assertion_failure(code_str = 0xfefdebdb "pc_desc != 0", file_name =

The full stack trace for the java_g crash is attached as threads.log.4.

This failure reproduces in a different way with the java cmd:

# Error ID: 43113F32554E54494D45110E4350500308 01

The ErrorID maps to: c1_Runtime1.cpp, 776

The code is in src/share/vm/c1/c1_Runtime1.cpp:
Runtime1::return_address_for_exception():

  // exception must have happened inside an nmethod
  CodeBlob* cb = CodeCache::find_blob(pc);
  guarantee(cb != NULL && cb->is_nmethod(),
    "exception happened outside interpreter, nmethods and vtable stubs");
