Internal Compiler Error with VS 2003

[t00fri]

For the first time, I get an internal compiler error with my VS 2003 compiler and latest Rev. 4404.

It happens in parseobject.cpp :

This line

if (planetData->getVector("LongLat", longlat) && system != NULL)

gives

c:\Develop\celestia\src\celengine\parseobject.cpp(765): fatal error C1001: INTERNAL COMPILER ERROR
(compiler file 'msc1.cpp', line 2708)
Please choose the Technical Support command on the Visual C++
Help menu, or open the Technical Support help file for more information


It's gone if I modify the line into

if (planetData->getVector("LongLat", longlat) )

and everything builds and runs fine. So what would be a workaround to make things continue to run with VS2003 ??

This is a bug in VC2003. But, there's also an error in the code, albeit an innocuous one. The function ParseObject used to take a parameter called system, but this parameter is no longer necessary. The test for system != NULL should have been removed when the function was changed. Ordinarily, the compiler would generate an error if a function tried to reference a non-existent variable. But, there's a C library function named system so the code continues to build. Since the system function is always defined, the expression system != NULL will always return true, making it completely extraneous and confusing. It shouldn't trigger an internal compiler error, but whatever . . . In this case, your modification is both a workaround for the compiler bug and what the code is *supposed* to look like. Please check in the change.

Done!

Now it's revision 4406.

You could check if there are updates for your VS 2003 or do you already have the latest version?
(Graphical interface: menu>Help>(search something that says updates or something like that) )

Of course.
