        Description

        An other case similar to 6968368. BCEscapeAnalyzer::do_analysis() calls ciMethod::get_method_blocks() which calls constructor ciMethodBlocks. This constructor allocates GrowableArray elements on stack (thread local resource area):

        _blocks = new(_arena) GrowableArray<ciBlock *>(block_estimate);

        As result when the method recompiled without EA _blocks->_data is NULL.
