[Bug tree-optimization/30394] New: FAIL: gcc.c-torture/execute/pr15262-1.c execution at -O2, -O3 and -Os

["danglin at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

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.
