Anyone else getting this error with the new blitzmax 1.37?

This happens in the cegui.mod directory.

The error occurs just after the IDE prints the

Compiling:CEGUIFalXMLEnumHelper.cpp

Don't know if this helps, but that's all the IDE says.

I got the exception_access_violation when trying to recompile the CEGUI module using the official bmk.exe -- it compiled without errors after replacing bmk.exe with Brucey's BMK NG.

Getting the same thing here on Win7 blitzmax 1.37 with the standard BMK..

When I try the same with a BMK built with debug, I get 'Unhandeled Exception:Attempt to access field or method of Null object'.
And the IDE pop the 'bmk.bmx' file, and highlight line number 110.

Function MakeModules( args$[] )

	If args.length>1 CmdError
	
	If args.length SetModfilter args[0] Else opt_modfilter=""
	
	Local mods:TList=EnumModules()
	
	BeginMake

	MakeMod "brl.blitz"
	
	For Local name$=EachIn mods
		MakeMod name  <------  THIS ONE
	Next
	
End Function

Hmmm... I suppose I should dig out an original bmk and try to track it down..

And failing on OpenSuse 11.1 with a segmentation fault to.

Didn't do a debug build of the BMK there, but guessing it's related..

EDIT: Ok, did a debug build, and fail with the same error as above.

The error is in an attempt to process a file stack.hh
It fails the ValidSourceExt() test, which causes the variable src_file in MakeSrc() to be Null.
That results in "Else If src_file.framewk" falling over for obvious reasons.

This is what the official bmk code looks like :

	Local src_file:TSourceFile=ParseSourceFile( src_path )

This is what my own bmk looks like :

	Local src_file:TSourceFile=ParseSourceFile( src_path )
	If Not src_file Return

Which is why mine doesn't crash in this case.

I would raise it as a Bug for Mark to fix :-)

Because my bmk likely gets a lot more workout than a typical installation (because of building, and rebuilding, and experimenting with new libraries), it's more likely to have hit these issues a long time ago.
Sometimes I might assume that a crash is due to my self, and therefore won't consider that the original code may be flawed.
