Description soldatov 2008-10-20 09:46:28 UTC

We have regression in inaccuracy tests from 17-10-2008.
Scenario:
- Launch IDE with fresh user directory
- Open Perl project
- Open config.h file in editor
==> This code is highlighted as error:
#if 42 != 1 && 42 != 42
#   include "Bletch: How does this C preprocessor concatenate tokens?"
#endif

P2 because I see this problem in RC1 also.

Comment 1 Vladimir Voskresensky 2008-10-20 12:30:33 UTC

most probably problem is in JVM. Problem is reproducible only on 
#java -version
java version "1.6.0_10"
Java(TM) SE Runtime Environment (build 1.6.0_10-b33)
Java HotSpot(TM) 64-Bit Server VM (build 11.0-b15, mixed mode)

everything is fine with 1.6.0_05 and 1.5.0_16

Looks like the problem with inlining of simple functions.

Reassigning to QA for evaluation of possible solutions.

Please evaluate

Comment 4 Alexander Pepin 2008-10-20 14:51:21 UTC

not a stopper for NB6.5 release as non-reproducible with previous java versions (earlier then 1.6.0_10) but should be
fixed in next release and in patch for NB6.5

Comment 5 julieg 2008-10-21 20:21:33 UTC

OpenSolaris 11/08 is going to have jdk1.6 update 10 as the default.
Does it make this bug a showstopper?

Comment 6 Leonid Lenyashin 2008-10-21 20:31:05 UTC

It does not look as a showstopper under any circumstances. And in this case the issue has been reported as purely Linux
issue (may be even only Linux64 issue), so I can not believe it affects OpenSolaris.
QA may want to double check it.

Leonid.

Comment 8 Vladimir Voskresensky 2008-10-22 13:44:30 UTC

just a note to QA: We can not fix this problem on our side, so not clear which fix could be included in 6.5 patch?

Comment 9 Vladimir Voskresensky 2008-10-30 12:13:03 UTC

I have found some tricks how to change code to be not overkilled by java machine 6 Update 10
