[Bug java/13824] New: gcj SEGV with simple .java program

public class pr13107_3
{
  public static void main(String[] args)
  {
    for (int i = 0; i < 1; i++)
      {
	try {
	  System.out.println(i);
	}
	finally {
	  if (i == 3)
	    continue;
	}
      }
  }
}


This will be in the libgcj test suite shortly.
This fails with a SEGV when compiled to native with "-c -O3".
It correctly compiles to bytecode.

[Bug java/13824] [3.3/3.4/3.5 Regression] gcj SEGV with simple .java program

Confirmed for 3.3, 3.4, and 3.5, this is a regression from 3.2.3.

The problem is in unsafe_for_reeval somehow with a tree of LABELED_BLOCK_EXPR.

Roger,

  Please apply for your proposed solution to 3.3.3.  It looks safe
to me.
