Fortunately the problem has nothing to do with object files. It's the linker
command file that does matter, so here is a simple way to reproduce the
segfault:
$ cat linker.cmd
MEMORY
{
RAM : ORIGIN = 0, LENGTH = 0x1
ROM : ORIGIN = 0x1, LENGTH = 0x1
}
SECTIONS
{
.data : AT(__data_image) {
*(.data*)
} > RAM
__rom_data_start = LOADADDR(.data);
.data_image (NOLOAD): {
__data_image = .;
. += SIZEOF(.data);
} > RAM
}
$ echo -n "" | ~/try/bin/sparc-elf-as -o test.o && \
> ~/try/bin/sparc-elf-ld -v -T linker.cmd test.o
GNU ld (GNU Binutils) 2.18.50.20080213
Segmentation fault (core dumped)

[Bug ld/5785] New: Spurious "section xxx overlaps section yyy"
LD version 2.18.x produces bogus "section .xxx overlaps section .bss", while LD
version 2.16.1 works just fine. Here is cut-down test to reproduce the problem:
$ echo -n | ~/try/bin/sparc-elf-as -o test.o
$ ~/try/bin/sparc-elf-ld -v -o test -T test.lnk test.o
GNU ld (GNU Binutils) 2.18.50.20080218
/home/osv/try/bin/sparc-elf-ld: section .xxx [0110 -> 011f] overlaps
section .bss [0110 -> 022f]
$ cat test.lnk
MEMORY
{
ROM: ORIGIN = 0, LENGTH = 0x1000
RAM: ORIGIN = 0x4000, LENGTH = 0x1000
}
SECTIONS
{
.data : AT(__data_image) {
. += 0x110;
} > RAM
.bss : {
. += 0x120;
} > RAM
.data_image (NOLOAD): {
__data_image = .;
. += SIZEOF(.data);
} > ROM
