Xiao-Feng Li updated HARMONY-5303:
----------------------------------

    Description: 
Latest update: This is Linux64 gcc bug. The Linux64 gcc issues are grouped at HARMONY-5416. It has nothing to do with a certain commit. That commit only makes Linux64 gcc bug to surface more frequently.

========================
The EUT3.3 suite - coreresources - start hanging on Linux x86_64 since r597313:
    Log:
     HARMONY-4325 : [drlvm][gc] Tick project concurrent GC improvement

(the latest passed revision by CC is 597106 (21-Nov-2007): 
http://people.apache.org/~smishura/r597106/Linux_x86_64/eut33/results/html/org.eclipse.core.tests.resources_linux.gtk.x86_64.html

the next test revisions (597436) demonstrated the crash (23-Nov-2007): 
http://people.apache.org/~smishura/r597436/Linux_x86_64/eut33/).

To reproduce the hang please follow the EUT run instrcution on Wiki page - http://wiki.apache.org/harmony/Eclipse_Unit_Tests_Pass_on_DRLVM - Chapter #1 and Chapter #2. You'll see in the output.txt that the suite run was terminated by timeout (this means the issues is reproduced).

Also I've found out that this hang is some kind of intermittent. I've run 'coreresources' 4 times on r597301 - it passed w/o hang all 4 times (although sometimes with some errors / failures). Running 'coreresources' on later revisions (starting 597313) shows the hang almost all of the time (19 hang on 20 runs).

Please note that the instruction in below Comment is a bit out of date (at least the link to archives was changed).
