OMC dies (SIGSEGV) on malformed within statement

[x05andre]

When loading a file (loadFileInteractiveQualified) with this content:

within ;
package root_package
end root_package;

OMC dies with a segmentation fault.

I'm running OMC revision 2149.

The following is the output from gdb:

Fixed it in revision 2515
within walker.g by adding a null test for "name".

within_clause returns [void *ast]
{

void * name= 0;

}

: #(WITHIN (name = name_path)? )

{

/* name_path is optional and before was no null test */
if (name == 0)

ast = Absyn_TOP;

else

ast = AbsynWITHIN(name);

}

;
