CONTEXT:
- GCC version: 4.3.0.
- Front end: gcj.
- Operating System: Linux Debian, kernel 2.6.17-2-686.
- Hardware: CPU Intel Pentium 4 Xeon, 3 GHz, 16 KB cache L1, 2 MB cache L2.
RAM: 1 GB.
There is a segment violation error when compiling the following code:
public class Fail
{
public static void main(String args[]) {
long a=5, b=2, r;
r=(a-b).toString();
}
}
The line number 5, r=(a-b).toString();, causes a segment violation during the
compilation:
gcj -C -Wall Fail.java
--
Summary: Segment violation in the “toString” method
on a mathematical expression
Product: gcc
Version: 4.3.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: java
AssignedTo: unassigned at gcc dot gnu dot org
ReportedBy: eduardo dot iniesta at aquiline dot es
GCC build triplet: i486-linux-gnu
GCC host triplet: Intel Pentium 4 Xeon
GCC target triplet: i486-linux-gnu

------- Comment #1 from tromey at gcc dot gnu dot org 2007-04-18 18:12 -------
Are you sure you are using gcj 4.3?
I see a SEGV with 4.1 and 4.2. But with 4.3 I see an error:
opsy. gcj -C Fail.java
Fail.java:5: error: Cannot invoke toString() on the primitive type long
r=(a-b).toString();
^^^^^^^^^^^^^^^^
1 problem (1 error)
(Note that, in all likelihood, we won't fix front end bugs of this nature
in 4.1 or 4.2.)

Thanks...
The exact version is:

Ok. You are running a version of gcj 4.3 from *before* the gcj-eclipse
merge. So, this is correctly marked as a duplicate.
If you update and rebuild, and follow the new instructions vis a vis ecj1,
you will get a working gcj.

Thank you very much, Tom.
I have updated GCC 4.3.0. Everything is well.
