Busybox v0.60.2 insmod gives segmentation fault without any messages when trying to load a loadable module

[Manish Lohani <mlohani@gmail.com>]

I have a driver loadable module which i am compiling with the same gcc
flags as used to compile a kernel for a MIPS R5432 based NEC board.

On the development machine, to compile files driver1.c and driver2.c:
$ mips_fp_le-gcc -fomit-frame-pointer -fno-strict-aliasing -G 0
-mno-abicalls -fno-pic -pipe -mtune=r5000 -mlong-calls -mips2 -Wall -c
driver1.c

$mips_fp_le-ld -r -o driver --printmap --cref driver1.o driver2.o

mips_fp_le-gcc (GCC) version 3.3.1
mips_fp_le-ld (GNU ld) version 2.14

I have Busybox v0.60.2 on the target.

On the target:
# insmod ./driver
Using driver
Segmentation fault
#

Does anybody have any suggestions as to what could be wrong?

Thanks in advance,
Manu
