[Radiance-general] Problems with Ubuntu's radiance distribution on amd64 platform

[Greg Ward]

Hi Lars,

Your backtrace is missing symbolic information telling what call was  
last made in Radiance.  It seems to have crashed in a sprintf()  
statement, which means it could have bombed while trying to print an  
error message.  You should recompile with the -g option and crash it  
again.

Just as a guess, you wouldn't happen to have any strings longer than  
127 characters in your material descriptions, would you?

This probably belongs on the dev list, so I'll cross-post and we can  
follow up there.

-Greg
