Description mal 2000-08-10 23:58:41 UTC
GCC segfault on the following program instad of giving an error message
gcc -O2 -S Y.java
gcc: Internal error: Segmentation fault (program jc1)
Please submit a full bug report.
See <URL:http://www.gnu.org/software/gcc/bugs.html> for instructions.

In the same time if I remove static
public static class UU it compiles OK

gcc --version
(RedHat 7.0 Public Beta)

---- Y.java
public class Y {
final UU v=new UU();
int u=0;
public static class UU {
protected UU()
public static void main(String [] args)
 System.err.println("Y CALLED");
 final Y x=new Y();
