[Bug ld/1046] New: Creates invalid Win32 applications (.exe) with gcc4

[ovidr at users dot sourceforge dot net]

Tried with:
GCC with gcj, precompiled with binutils 2.15.94:
http://www.thisiscool.com/gcc_mingw.htm
http://www.thisiscool.net/gcc40-20050324.tar.bz2

Also tried with a self compiled gcc 4.0 and with binutils head (july 1st 2005).

Most applications I compile and link produce working executables. This is true 
at -O0 and -O1 with gcc.

Specific larger applications compile and link, but when compiled -O1 and above, 
the resulting .exe is reported to not be a valid win32 application. Win32 
reports:

app.exe is not a valid Win32 application.

Looking in the .exe (view it in hex), the .rdata section has more than /1500 
entries. I don't know what they are, but when the number exceeds approx /1500, 
the apps are no longer valid.  (just an observation)

Attached is a simple big.java file.  Compiles and links fine.  The 
resulting .exe works fine at -O0, but not -O1 and above on win32.  The 
resulting binary works fine on linux at any optimization level.

gcj -O1 --main=big big.java -o big
big.exe is not a valid Win32 Application

It is just a bunch of strings of increasing length. This seems to fill
up the .rdata section. With less than 150 strings the .exe works.  At -O0 it
works. More than 175 strings and -O1 or above and the .exe becomes invalid.

I don't know what else to try, but it seems to be a binutils (as or ld) bug 
(gcc bugmaster suggests the same).
