periodic exception in execnt.c

I have been getting the occasional exception in bjam.exe, so I have 
switched to using a debug build. This has caught an exception in execnt.c:

[line]
[530] f = fopen( cmdtab[ slot ].tempfile, "w" );
[531] fputs( string, f ); // <== HERE
[532] fclose( f );

The VC++ IDE is reporting that f is 0.

cmdtab[slot]: name value type
pid	0	int
func	0x0040c660 make_closure(void *, int)	void (void *, int)*
closure	0x00d07904	void *
+	tempfile	0x00511f80 "c:\DOCUME~1\User\LOCALS~1\Temp\jam1264-00.bat"	char *

The resolution would be to add:

[530a] f = fopen( cmdtab[ slot ].tempfile, "w" );
[530b] if( f == 0 ) report-error-and-exit;
