Hi,

When I run qsub with the -W option, it crashes with the following error:

This happens if and only if I use the following in the script (or as -W on the
commandline)

#PBS -W
stagein=CREAM798436615_jobWrapper.sh@gb-ce-ams.els.sara.nl:/opt/glite/var/cream_sandbox/ops/_O_dutchgrid_O_users_O_sara_CN_Ernst_Pijper_ops_Role_lcgadmin_Capability_NULL_ops001/79/CREAM798436615/CREAM798436615_jobWrapper.sh,stagein=cream_798436615.proxy@gb-ce-ams.els.sara.nl:/opt/glite/var/cream_sandbox/ops/_O_dutchgrid_O_users_O_sara_CN_Ernst_Pijper_ops_Role_lcgadmin_Capability_NULL_ops001/proxy/12881031212E589696sam2Dwms2Egrid2Esara2Enl13921030130163

When I remove one char or add at least 2 chars at the end, all goes well.

We have had a look and it seems that the source of this bug is the following in
qsub.c (2.5.3 version)

In the function smart_strtok (line 375 in qsub.c)
tmpLineSize = (line == NULL) ? strlen(*ptrPtr+ 1) : strlen(line) + 1;
It seems this needs to be:
tmpLineSize = (line == NULL) ? strlen(*ptrPtr)+ 1 : strlen(line) + 1;


We have seen this error in 2.4.10 and 2.5.3.
2.3.7 works fine, although we have not looked in the sources.
