Browser bug

[Jean-Pierre Dussault]

Hi,

in order to compile the browser, I had to manually add 
$SATHER_HOME/System/Platforms/linux/header.h  to sather.h in the 
generated code in sabrowser.code.

Once compiled, the browser crashes most of the times. For instance, it 
crashes on sabrowser.module, it crashes on all-classes.sa and the error 
message is always the same, except for the class name that made it 
crash. The browser works fine on test.sa(in the Browser directory), and 
on sacomp.module. Unfortunately, it does not work for the project I am 
developing.

I   work under (K)Ubuntu 8.04.

The error message is always

   May crash later:CLASS_NAME
   ./Sather/browser.sa:837:Attr access of void as.source1


For instance, for all-classes.sa , :

   address@hidden:~/import/sather-1.2.3/Browser$ ./sabrowser
   all-classes.sa
