> Dacapo xalan bechmark fails with the assertion on DRLVM run in '-Xem:server' mode because
C heap is exhausted. The assertion fires compiling the following method:
> org/apache/xalan/processor/XSLTSchema::build()
> The method contains ~35000 operands and the graph coloring register allocator needs ~35000^2
bytes to compose an internal data structure. 2 improvements could be made here:
> 1. Change byte usage to BitSet.
> 2. Fall back to binpack RA when compiling methods with many operands.
> This is a strightforward approach, probably there can be a more elegant solution.
> The log for the failure is following:
> Windows reported exception: 0xc0000005
