Hi Tom, First, let me say that giving me access to your Intel MacOS-X was _greatly_ appreciated. There is no way that I would have understood the problem I eventually found through email exchanges describing the problem!! "For the files": the problem I found was that the McIDAS startup process widget, 'mcimagem', was generating a bus error under certain circumstances. I took a hard look at the source code for the routine, mcimagem.c, and did not see anything obviously amiss, so I was left scratching my head. Through experimentation, I discovered that 'mcimagem' runs correctly in a mini-McIDAS environemnt like: mcenv mcimagem -run This told me that the McIDAS environment needed by 'mcimagem' was either not created fast enough when 'mcimagem' runs by itself, or was getting torn down before it should. Having 'mcenv' run 'mcimagem' insures that a full McIDAS environment is created before 'mcimagem' is run. So, I had to modify the McIDAS startup script 'mcidas' (created from 'mcstart.gui' by the make process) to run 'mcimagem' from 'mcenv'. As I write this, I am rebuilding the v2007 distribution from source just to make sure that I did not make a stupid mistake during my experimentations on buran. I will let you know tomorrow if everything is up to snuff.
