<great sigh of relief> Excellent. Thanks for your work, I was completely out of ideas on this. :) > Ok, I've test compiled the simgear/nasal library using gcc on IRIX > and linked it with the MIPSpro build version of FlightGear and it's > working like a charm. Now remains the question, is it an exploited > gcc bug/feature or is it really a MIPSpro bug? I've personally built and tested it using the Sun Studio compiler on Sparc, and the windows builds are done using MSVC. That proves nothing, of course, but if code were a democracy MIPSpro would be losing 3:1. :) Note that the naRef structure is a nested union, and the code makes heavy use of structure assignment of these things. That's not a common idiom (most other interpreters just use casts), so I wouldn't be shocked if it triggered a bug or two. There's one spot in there already (I forget who found it -- not me, anyway) with a workaround for a gcc 2.95 code generation bug. If you want to continue tracking this down, you could try starting with a gcc library, and replace each .o file in turn with a MIPSpro one to figure out where the faulty code generation is (it might be more than one location, of course), then start moving code out symbol-by-symbol until you zero in on the location. Then we can try to rewrite it so it compiles correctly.
