The generated code just calls malloc and then abort:
(gdb) disass main
Dump of assembler code for function main:
0x00002b98 <main+0>: stw rp,-14(sp)
0x00002b9c <main+4>: ldi 8,r26
0x00002ba0 <main+8>: b,l 0x2b68 <malloc>,rp
0x00002ba4 <main+12>: ldo 40(sp),sp
0x00002ba8 <main+16>: ldi 1,r19
0x00002bac <main+20>: b,l 0x2b80 <abort>,rp
0x00002bb0 <main+24>: stw r19,4(ret0)
0x00002bb4 <main+28>: nop
The RTL is wrong in .expand.
