Subject: [Bug tree-optimization/30394]  New: FAIL: gcc.c-torture/execute/pr15262-1.c execution at -O2, -O3 and -Os
Date: Sat, 06 Jan 2007 19:42:00 -0000	[thread overview]
Message-ID: <bug-30394-276@http.gcc.gnu.org/bugzilla/> (raw)

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.

First seen in 120133.  Last build without this fail was 120074.
