Summary: Segmentation fault if using gcj with -Xassembler

Initial Comment:
Hi!

If I create a file named for example 'aaa' with only a 
newline ('echo. > aaa') and run gcj on it as follows:

gcj aaa -Xassembler --help

it crashes with a segmentation fault:

Die Anweisung in "0x77f645cc" verweist auf Speicher in 
"0x6c626d65". Der Vorgang "written" konnte nicht auf 
dem Speicher durchgeferden.

(The command at "0x77f645cc" couldn't write to memory 
in "0x6c626d65").

Output of ld -v:
GNU ld version 2.15.90 20040222

gcj nul.java -Xassembler --help -v
crashes without any output, trying to write to memory at 0.
Same when I add spaces around nul.java.
Same when I use a file named 'aaa'.

gcj.exe is segfaulting. Remember i'm calling gcj -Xassembler 
--help. If i use gcc -Xassembler --help, it doesn't generate a 
segfault. It also doesn't generate one if I use Mohan's 3.5 build 
(http://www.thisiscool.com/gcc_mingw.htm, gcc version 3.5.0 
20040629 (experimental)). So this might be already fixed?

Hi,

I can't reproduce this.  What program is segfaulting?  I 
assumed it was ld because without a suffix on the file and no -
xlang switch, gcc just passes it on to ld.
