[Bug java/43055] New: 'jc1: internal compiler error: Segmentation fault' using gcj -fprofile-arcs

[eldenc at tucsonembedded dot com]

Appear to be a recurrence of an older 'fixed' bug
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=8260
I will attempt to compile the latest version gcj and see if the problem exists
there as well.
================ test.java ================
public class test {
  public static void main(String[] args) {
    System.out.println("Hi Elden");
  }
}
============================================
gcj -fprofile-arcs -g --main=test test.java

Program received signal SIGSEGV, Segmentation fault.
0x08158cf6 in coverage_checksum_string (chksum=0, string=0x0)
    at /home/richard/src/trunk/gcc/coverage.c:484
484       for (i = 0; string[i]; i++)

Looks like the current function does not have a location.

536     {
537       expanded_location xloc
538         = expand_location (DECL_SOURCE_LOCATION (current_function_decl));
539       unsigned chksum = xloc.line;
540     
541       chksum = coverage_checksum_string (chksum, xloc.file);
542       chksum = coverage_checksum_string
543         (chksum, IDENTIFIER_POINTER (DECL_ASSEMBLER_NAME
(current_function_decl)));
544
