Bug#165635: gcj-3.0 : segmentation fault on compiling bad program

[rOBie <robie@bzh.net>]

Package: gcj-3.0
Version: 1:3.0.4-7
Severity: important

When compiling the file :
---------begin-of-essai_bug.java--------------
class essai_bug {
   public static void main (String[] argLigneDeCommande) {
        int i=0;
        int a;
        int b=1;
        for (i=a; i<=b; i++){
	    System.out.println("i = "+i);
	}
   }
}
---------end-of-fichier-essai_bug.java-----
which is a bad java file because 'a' has no value.

the compiler "gcj -C essai_bug.java" has a segmentation fault with the error message :
-----begin of error message------------------------
essai_bug.java: In class `essai_bug':
essai_bug.java: In method `essai_bug.main(java.lang.String[])':
essai_bug.java:2: Internal error: Erreur de segmentation
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://www.gnu.org/software/gcc/bugs.html> for instructions.
------end of error message-------------------------
instead of a warning about the initialisation of the 'a' variable

~La ligne de commande  : "gcj -C essai_bug.java" rend :

~class essai_bug {

~	}
~   }
~}
~---------fin-de-fichier-essai_bug.java-----

~alors qu'on devrait avoir juste un message indiquant que a n'est pas initialisé.
