I don't get this anymore with gcc*-4.0.0-1 and
eclipse-platform-3.1.0_fc-0.M6.11.  Closing.
Comment 3 Ben Konrath 2005-04-26 17:20:39 EDT
This is still happening with "Eclipse Application" - same stack trace.
Comment 4 Ben Konrath 2005-04-28 13:44:03 EDT
Archiving what I've got so far ... 

Combo.getText() in PerpectivesTab.updateConfigFromCombo() is returning a string
with garbage at the end (Ω) when run with gij. This causes the NPE because it's
not recognized as a string. Investigating this further it seems as though the
string is getting corrupted somewhere.

I made a stand-alone test for Combo.getText() and the string is not corrupt with
both VMs. However, I did notice that OS.strlen() is getting called an extra time
with gij. I'm not sure if this is related but I'll going to keep digging.

Comment 6 Ben Konrath 2005-04-28 17:17:24 EDT
The small app actually does have the corrupted string, just not all the time.
When the string is corrupted I also see:

patch to work around the NPE

I think it might be a good idea to work around NPE temporarily until the cause
of the corrupt string is found. Andrew, what do you think?
Comment 9 Andrew Overholt 2005-04-29 17:25:37 EDT
I think that's a good plan for the short term.
Comment 10 Ben Konrath 2005-04-30 16:49:20 EDT
Ok, that patch will be in 3.1.0_fc-0.M6.13
Comment 11 Andrew Overholt 2005-05-01 12:43:26 EDT
Verified in 3.1.0_fc-0.M6.13.

Ben, I'll leave it up to you to close this bug or leave it open as you see fit.
Comment 12 Ben Konrath 2005-05-02 00:37:10 EDT
Hey Andrew,

Billy pointed me to the actual cause of the problem (see the upstream bug listed
below). I'm going put the proper fix into a new version so we shouldn't put
3.1.0_fc-0.M6.13 into FC4.
Comment 13 Ben Konrath 2005-05-02 17:40:37 EDT
Ok, I removed my patch and added the upstream fix for 3.1.0_fc-0.M6.14. Andrew,
can you verify this fix and close the bug if it works. Thanks, Ben
Comment 14 Andrew Overholt 2005-05-03 13:33:47 EDT
This works for me.  Closing.
