[Description Machiel Groeneveld 2004-10-13 00:31:38 UTC]

After emerging eclipse-sdk-3.0.1-r1 on amd64 (I've tried both sun-jdk-1.5.0 and blackdown 1.4.2), I get a segmentation fault when trying to start eclipse-3.

Reproducible: Always
Steps to Reproduce:
1. Emerge eclipse-sdk
2. run eclipse-3
3. Also java -cp startup.jar org.eclipse.core.launcher.Main

Actual Results:  
/usr/bin/eclipse-3: line 36:  6935 Segmentation fault      ${ECLIPSE_BIN} $*

Expected Results:  
eclipse starts normally

Portage 2.0.50-r11 (gcc34-amd64-2004.1, gcc-3.4.2, glibc-2.3.4.20040808-r1, 2.6.

Stacktrace reveals that problem occurs in strdup() call in fixEnvForMozilla(). Since I am still looking into how to get my own patch into an ebuild, I have not verified this yet, but the problem may be because there are no prototypes for getenv() which introduces conversions from 64 to 32 back to 64.
It seems possible to avoid the problem by making sure environment variables MOZILLA_FIVE_HOME and LD_LIBRARY_PATH are not set when starting eclipse.

[Comment 2 Johan Backlund 2004-10-17 14:44:55 UTC]

Adding include file stdlib.h to files using getenv() seems to do the trick.

Created attachment 42127 [details]
Suggestion of new ebuild and patch to fix 64bit problems with getenv()

I do have some amateur version of a new ebuild with patch and digest. I am
attaching it here in case it can be useful to someone.

Okay, thanks! I will apply this and have the amd64 people test it.

[Comment 5 Olivier Bilodeau 2004-10-22 14:40:17 UTC]

I experienced the same problem.
The stated workaround (unset of MOZILLA_FIVE_HOME and LD_LIBRARY_PATH) worked.
I haven't really used the program so I don't know if something else is broken.

Waiting for a fixed version so I can test it.

[Comment 6 Mike Messmore 2004-11-06 21:49:29 UTC]

Same issue here.  Resolved by running: 
unset MOZILLA_FIVE_HOME;
eclipse-3

Committed.
