I can reproduce this in the mainline (20031007) on powerpc-apple-darwin7.0 so this is a generic 
bug.

Could not reproduce with gcc 3.4 20030930 on linux x86 native, so the bug may have been 
introduced since then.

Note both Darwin and cygwin do not support weak symbols so it might be related to that.

Might be fixed by:
	* varasm.c (notice_global_symbol):  Fix handling of variables; avoid
	re-computing of variable.

Can you try again, I would but I am tracking down another bug?

Compiling GCC isn't my forte.

I tried to compile GCC 3.4 from CVS, but it failed today:

I guess it still happens, since the bug I reported was marked as a duplicate of 
this one and that was a freshly compiled GCC 3.4 from CVS as of today.

I can't duplicate this on Linux.

Please use -save-temps and let me have the .s file.

I should say this has to be with no weak symbols in the target like powerpc-apple-darwin and 
i686-pc-cygwin.

This is strangerer, and strangerer.

When I add the -save-temps argument I get no error message.

And probably an invalid output. the .s file is too big to attach to this bug-
report.


Although I have used two different computers(the main difference being 256MB 
vs. 512MB ram) for testing against this problem, I have a sneaking suspicion 
that this compile takes way longer than normal.

I verified that the same problem happens with my Linux -> Windows cross 
compiler, so at least the problem should be debuggable on Linux.

My Linux->Windows cross compiler is built per Mohans instructions.

Has anyone been able to figure out roughly when this regression was introduced? It would be 
useful to know what patch caused it.

Ah!

The problem seems to be files in the jar which start with "."

This is boot.jar from Eclipse 3.0M4:

http://download.berlios.de/pub/mldonkey/z/boot.jar

This is gcc 3.4 (win32): gcc version 3.4 20031109 (experimental)

gcj -c boot.jar -o boot.o 

C:\DOCUME~1\Main\LOCALS~1\Temp/ccUFdaaa.s: Assembler messages:

`__GLOBAL__I__ZN3org7eclipse4core4boot10BootLoader18__U3c_clinit__U3e_Ev' is

Works fine with 3.3.1.  There are no .* files in boot.jar that I can see.
