Description Vladimir Kvashin 2015-07-21 17:23:31 UTC 
I've got a stable OutOfMemoryError when code model preprocesses
cnd.modelimpl/test/unit/data/org/netbeans/modules/cnd/modelimpl/trace/FileModel3Test/delay.c
Comment 1 Vladimir Kvashin 2015-07-21 21:08:47 UTC 
Unfortunately .hprof file is 1G, so I can not attach it here. Nut it is available by request.

I also wasn't correct enough stating the problem. I launched o.n.m.cnd.modelimpl.impl.services.ServicesTest and got OOME on another test. But yourkit showed me that it was parse of delay.c who consumed huge amount of memory.
Comment 2 Vladimir Kvashin 2015-07-21 21:20:18 UTC 
I temporarily commented out the content of delay.c to allow other tests running:
http://hg.netbeans.org/cnd-main/rev/a7be0e70f00d
Please restore it as soon as the bug is fixed.
Comment 3 Vladimir Voskresensky 2015-07-22 07:29:54 UTC 
I will have a look
Comment 4 Vladimir Voskresensky 2015-07-22 07:51:47 UTC 
Test requires 6G and runs 120(cold)/90(hot) secs.
Native one requires ~2G and runs 4 sec
The output of -E is empty. It is compile time "delay" for compilers using PP magic
