Summary: GDK/M4/PF: GDK assertion in PF/XQ tests since 2007/11/15

Initial Comment:
Since Nov 15 2007 (i.e., after checkins on Nov 14 2007) PF/XQ tests
pathfinder/modules/pftijah/Tests/cleanup.milS
pathfinder/tests/BugTracker/Tests/pf_add-doc_property_error.SF-1706438.xq
fail with

Mserver: .../MonetDB/src/gdk/gdk_bbp.mx:1284: incref: Assertion 
`BBP[(((int)(i))>0?((int)(i)):-((int)(i)))].refs+BBP[(((int)(i))>0?((int)(i)):-((int)(i)))].lrefs'
 failed.

Cf.,

Since there was only one Pathfinder checkin on Nov 14 2007 by Niels related to 
his GDK_init and (un)aligned memory changes in GDK on the same day, I (for now) 
assume this a GDK bug, and assign it to Niels.

I haven't done any further analysis, yet.

Better look at (e.g.)

http://monetdb.cwi.nl/testing/projects/monetdb/Current/pathfinder/.mTests10
3/GNU.32.32.d-Fedora6/modules_pftijah/cleanup.err.00.html
http://monetdb.cwi.nl/testing/projects/monetdb/Current/pathfinder/.mTests10
3/GNU.32.32.d-Fedora6/tests_BugTracker/pf_add-doc_property_error.SF-1706438
.err.00.html

as the GNU-compiled 64-bit, 64-bit OID version of Pathfinder (also when
compiled with optimization enabled) seems to suffer from the gcc bug
reported in
[ 1830366 ] gcc 4.1/4.2 produces wrong code on FC6 & RHEL4WS
