SIGSEGV on GCTaskThread in jdk 6u18

[Janda Martin]

Please can you help me. I experienced several crashes on GCTaskThread in latest Java6u18 when running IntelliJ IDEA (not only). 64bit linux, 32bit jvm, 4 core processor
 I create new bug report with Review ID: 1699960.

  Is there any -XX options to help diagnose this problem. It looks like regression from 6u17 (maybe) or 6u16 (sure).

hs_err log files are attached.

  Thank you.
    Martin
