Hi,
When running the libtool regression tests, I get the following error:
gcj -shared -Wl,--whole-archive ./.libs/liba1.a ./.libs/liba2.a
-Wl,--no-whole-archive -Wl,-soname -Wl,liba12.so.0 -o .libs/liba12.so.0.0.0
./.libs/liba2.a(A2.o):(.rodata+0x0): multiple definition of `java resource
.dummy'
./.libs/liba1.a(A1.o):(.rodata+0x0): first defined here collect2: ld returned 1
exit status
Looking at liba1.a I see:
Relocation section '.rela.text' at offset 0x1ad0 contains 3 entries:
Offset Info Type Sym. Value Sym. Name +

Symbol table '.symtab' contains 54 entries:
Num: Value Size Type Bind Vis Ndx Name

There is nothing called "dummy" in the source file. The source
file is:
public class foo1 {
public static void main(String[] argv) {
A1 a1 = new A1();
}
}
It can also be reproduced with a file that just
has "public class foo1 {}"
I get this error with Debian's 4.3.4-4. The version 4.3.2-2 does not generate
that symbol. An old build log of libtool with gcj version 4.3.3-3 also does
not show the error.
