State-Changed-Why:
    This looks like recode bugs (even ones which have been fixed
    in recode-3.6). Particularly applemac.c and ibmpc.c missing
    return statement at end of their module_* routines.

>Description:
	I have tried to compile GNU recode-3.5 using gcc-3.1 on my machine
	(glibc-2.2.5, target i686)

	The result was immediate segfault of compiled recode:
	recode latin-2..latin-1

	Note that recode was compiled using --enable-shared --disable-static --prefix=/usr

	Buggy codes:
	    gcc-3.1 -O
	    gcc-3.1 -O2
	    gcc-3.1 -O3
	Correct codes:
	    gcc-3.1 -O0 -g
	    gcc-3.0.4 -O3

(Both compilers was compiled from CVS tags: gcc_3_0_4_release and
gcc_3_1_release) and self-recompiled using -O3.)

(Sorry for vague report, but I am not able to detect, which part of recode causes the problem.)
