R devel - Feb 2010 - src/main/par.c (PR#14214)

At lines 1154-5 in par.c (at the latest svn revision 47460), in function
do_par():

    if (new_spec && GRecording(call, dd))
	GErecordGraphicOperation(op, originalArgs, dd);

if the call GErecordGraphicOperation gives rise to a garbage collection
(as it may), the return value of do_par will be trashed.

(Discovered during CXXR development.)
