>Summary: PF/probxml: Memory corruption in MXQ 0.20

Initial Comment:
The attached query (no document needed) crashes the server with:
MonetDB>*** glibc detected *** malloc(): memory corruption: 0x09b9da78 ***
If you set the $pta and $ptb variables at the bottom to $testworks1 and 
$testworks2 instead, then the query works fine.

I just downloaded and compiled (on Suse Linux) a fresh stable version of 
MonetDB/XQuery 0.20 by checking out the following braches of modules from 
sourceforge:

buildtools branch MonetDB_1-20
MonetDB branch MonetDB_1-20
clients branch Clients_1-20
MonetDB4 branch MonetDB_4-20
pathfinder branch XQuery_0-20

Before others (also) loose time on investigating this problem:

Please note that the attached query requires the non-default "probxml"
extensions, i.e., pathfinder needs to be configured with "--enable-probxml"
!

(I currently don't have such pathfinder readily compiled, and not much
time to compile one right now...)

CVS head version runs the query correctly once, but crashes upon a second
try. Looks like coincidence.
