is there anybody out there, who is also running PV-Wave v8.51 on Etch? Our PV-Wave based application has been running successfully until Etch' mid-march version. However, PV-Wave now segfaults when calling the `tv' procedure to display an image. This is a screen capture when running the `tv' demo from the PV-Wave documentation:
Hmm. PV-wave is bug compatible with IDL! You might want to consider gdl, which has different bugs for your entertainment. IDL's tv is failing too, as are many other apps. For me, Friday the 13th updates marked the death of IDL on FC5, debian etch, and gentoo. The problem appears be related to the patches for "Multiple integer overflows in the XGetPixel() and XInitImage functions" (CVE-2007-1667). The patches add argument sanity checks, and appear to be revealing many insane calls in apps using these functions. For me: IDL> tv, bytarr(9,9) triggers the bug See the recent posts in <http://ittvis.com/forum/message.asp?fmid=2267>

I would appreciate it, if someone, who has a PV-Wave installation at his fingertips, would be willing to try reproducing this problem on latest Etch and share his findings with me (or even better: with the list).
