[Bug bootstrap/16546] New: Solaris 10/x86 libobjc bootstrap failure: invalid assembler code

["gcc-bugzilla at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

Between 20040618 and 20040709, mainline bootstrap on i386-pc-solaris2.10
started to fail in libobjc:

Assembler: NXConstStr.m
	"NXConstStr.s", line 66 : .size argument has negative value
	"NXConstStr.s", line 96 : .size argument has negative value

The crucial difference between the assembler outputs (around line 66) is
like this:

        .type   _OBJC_INSTANCE_METHODS_NXConstantString, @object
-       .size   _OBJC_INSTANCE_METHODS_NXConstantString, 32
+       .size   _OBJC_INSTANCE_METHODS_NXConstantString, -1
 _OBJC_INSTANCE_METHODS_NXConstantString:

I haven't yet started looking for the culprit patch.

Architecture: i86pc

How-To-Repeat:
Bootstrap mainline as described above.
