#628 Segmentation fault if using gcj with -Xassembler

[nlite]

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 durchgeführt werden.

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

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.

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?

What does this command show
gcj nul.java -Xassembler --help -v

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'.
