What steps will reproduce the problem? 1. clone the qt4 repo and add it as cpp project with autotools to eclipse 2. reconfigure the project 3. watch the errors pile up in error log -- Error Details --

This should be fixed in the upcoming CDT 8.4, could you try that version? You can go to Help > Install New Software and add this update site: http://download.eclipse.org/tools/cdt/builds/8.4/nightly
The NPEs are gone but the following 2 errors remain. Should I open a new bug report for them?

Patch that fixes the error from comment 4: https://git.eclipse.org/r/24512 Regarding the error from comment 3: it would be very helpful to have a reduced example that triggers it. Note that since this exception is caught, it should not have any negative effects beyond perhaps incorrect name resolution at the spot that triggered the exception.
for the exception from comment 3 i have found that when you do Index > Update with modified files on the folder qt/src/3rdparty/webkit/Source/ThirdParty/ANGLE/src/libGLESv2 it will trigger several of them after ~5 sec. You might need to run a full index once though. OTOH I have no idea which source really triggers them as the error description is rather vague. Better error messages might help. The error from comment 4 is gone with the latest nightly of CDT.
