[daip] VBGLU bug

[Cormac Reynolds]

Hi,

I think I've located a bug in the VBGLU task. Occasionally I find it crashes
with the classic 'ZABORS: signal 11 received' message. This seems to happen
when VBGLUing fairly large files. The actual segmentation fault appears to
happen on line 1230:

        RINTIM(I+VICNT) = BUFOUT(IPT+JLOCT)

where (IPT+JLOCT) points beyond the length of the BUFOUT array. I found that
changing the value of OUTSIZ (the length of the BUFOUT array) to a very large
number eventually fixed the problem, though I have no idea what a
reasonable number for OUTSIZ would be or if another solution is better.

If necessary I can provide you with a dataset that triggers the problem.
Unfortunately it is quite large (~10 GB), but I can put it on our ftp server if
you need it.

regards,
Cormac.
