Description of problem:

doxygen 1.8.4 goes to an inifinity loop inside a koji build when generating documentation.

This bug can be reproduced only in a specific case :
- The platform must be RHEL6 / SL6 
- mock must try to build for a rawhide target
- the src code used for the documentation generation must contains a commented loop ( ex : while(ret <0 ) )

This issue is not minor, all koji builds are under EL6 and are used to build  fedora rawhide, this issue can hangs any src.rpm koji build with a doxygen generation for rawhide.


Version-Release number of selected component (if applicable):
doxygen-1.8.4-1

How reproducible:

On RHEL6/SL6 :

wget http://grid-deployment.web.cern.ch/grid-deployment/dms/lcgutil/tar/davix-0.2.0-1.el5.centos.src.rpm

mock -r fedora-rawhide-x86_64 davix-0.2.0-1.el5.centos.src.rpm

On Koji :


wget http://grid-deployment.web.cern.ch/grid-deployment/dms/lcgutil/tar/davix-0.2.0-1.el5.centos.src.rpm

koji build --scratch rawhide davix-0.2.0-1.el5.centos.src.rpm 


Example :
http://koji.fedoraproject.org/koji/taskinfo?taskID=5471071



Actual results:

-> infinity loop

Expected results:

-> finished with warnings

Additional info:

-> occures only on a EL6 mock building for rawhide, not on a f18 mock building for rawhide
