While building pnetlib with kernel-fp profile I got:

So I build the pnetlib with full profile...

I have tried and got this:
# ./ilrun -L /var/libs/ test.exe
test.exe: invalid entry point
__alloc_pages: 0-order allocation failed (gfp=0x1d2/0)
VM: killing process ilrun
Segmentation fault

But I do not think that the problem is related to memory. The big
consumption of memory and segfault occurs in context (your test.exe) or
image (my hello.exe) destroy functions which are triggered by ilrun not
being able to link or find the correct symbols.

Also I stepped thought the code which I suspect as malfunctioning with
gdb on my ia32 and on CRIS and found that on CRIS in the function 
ILTypeIdentical in image/meta_types.c line 514, we ALWAYS return in 541:

       if(ILType_IsPrimitive(type1))    <---- This is alway true
        {
                return (type1 == type2);
        }

while on my ia32 box this dose not happen.

Any ideas?
