large objects cause jdk crashes

Next tests fails with unexpected exception or crash with SIGSEGV with JDK 1.5.0_34 b01_j4b:
gc/gctests/LargeObjects/large003
gc/gctests/LargeObjects/large004
gc/gctests/LargeObjects/large005

These tests also fails with JDK 1.5.0 FSC.

These three tests were not executed with JDK 1.5 before because they were added to testbase as part of testbase backporting process.
Tests fails the same way as with JDK 1.6.0_13 (for which similar CR 6845368 was resolved) and it seems to be the same issue.
New CR created because CR 6845368 is currently closed. We need it for failure matching.
