Does this problem occur on J2SE 1.3, 1.4.x or 1.5? Yes / No (pick one)
No (bug specific to the new G1 collector)
Operating System Configuration Information (be specific):
Windows Vista SP1 [6.0.6001], Brazilian Portuguese, fully patched
Hardware Configuration Information (be specific):

Bug Description:
Testing again the new "Garbage First" collector, but now in JDK 6u14 and also enabling the new Escape Analysis option, I executed the same benchmark of bug 6775807. The VM crashed immediately. The crash dump file seems to reveal a C2 bug, likely in Escape analysis stack-allocation code that interacts with G1. I executed the test again with G1 but no Escape analysis and it works; with Escape analysis but without G1 and it works too. I repeated the test with G1 and Escape analysis and it crashed again exactly in the same point, in the compilation of ParseUtil.decode().
Steps to Reproduce (be specific):
See remarks for bug 6775807.
