I can't reproduce this error (gcc 2.4.2/libg++ 2.3/ SunOS 4.1.2)

Configured as: ./configure --prefix=/usr/local/gnu sun4

(But this gives the same config files as --target=sparc-sun-sunos4.1.2)

The only thing different from our configuration is the libg++ version.

Other points of interest: which version of as do you use?

GNU as? SunOS 4.1.2 as?  SPARC compiler 1.x or 2.x as?

The code gcc is trying to compile looks like:

	typedef void entry_pt();

	extern entry_pt x1 __asm__ ("__GLOBAL_$I$tie__C3ios");

	entry_pt * __CTOR_LIST__[] = {
		(entry_pt *) 1,
		x1,
		0
	};

	extern entry_pt x2 __asm__ ("__GLOBAL_$D$tie__C3ios");

	entry_pt * __DTOR_LIST__[] = {
		(entry_pt *) 1,
		x2,
		0
	};

	extern entry_pt __main;
	entry_pt *__main_reference = __main;

And results in the following assembly on my machine:

	gcc2_compiled.:
	___gnu_compiled_c:
		.global ___CTOR_LIST__
	.data
		.align 4
	___CTOR_LIST__:
		.word   1
		.word   __GLOBAL_$I$tie__C3ios
		.word   0
		.global ___DTOR_LIST__
		.align 4
	___DTOR_LIST__:
		.word   1
		.word   __GLOBAL_$D$tie__C3ios
		.word   0
		.global ___main_reference
		.align 4
	___main_reference:
		.word   ___main


CHeck whether gcc and your assembler grok the above code.
(And whether gcc produces the correct assembler output)


My g++ -v test.cc -o test-cc output is:
