Bug 168587 – sys-devel/gcc-4.1.1 - gcj gives a segmentation fault when compiling with -fprofile-arcs flag

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Stephen Torri 2007-02-27 15:31:03 UTC]

When I attempt to compile a java source file with gcj and use the -fprofile-arcs flag I get a segmentation fault.

Reproducible: Always

Steps to Reproduce:
1. gcj --main Fibonacci Fibonacci.java -fprofile-arcs


Actual Results:  
storri@base ~/Documents/StephenTorri/comp6210 $ gcj --main=Fibonacci Fibonacci.java -fprofile-arcs
Fibonacci.java:1: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://bugs.gentoo.org/> for instructions.


Expected Results:  
Program to compile.

class Fibonacci {

        public int calculate ( int n )
        {
                int output = 0;

                if ( n > 1 )
                {
                        output = calculate ( n - 1 ) + calculate ( n - 2 );
                }
                else
                {
                        output = n;
                }

                return output;
        }

        public static void main ( String[] inc )
        {
                if ( inc.length > 0 )
                {
                        Fibonacci f_ref = new Fibonacci();

                        int n = Integer.parseInt(inc[0]);
                        while ( n != -1 )
                        {
                                System.out.println( "Calculated fibonacci number: " + f_ref.calculate ( n ) );
                                n--;
                        }
                }
                return;
        }
}

This works fine with gcc-4.3
