The suspicious code is around: bl g_hash_table_new(PLT) mov sl, r0 add r0, sp, #32 bl g_mime_decode_lwsp(PLT) ldr r3, .L146+24 ldr r1, [sp, #4] str r3, [sp, #16] ldr r3, [sp, #32] ... .L146: ... .word .LANCHOR0-(.LPIC18+4) The 'ldr r3, .L146+24' references the offset. The value is spilt to the stack before the normal `add r3, pc` and doesn't seem to be used afterwards. The work-around is to compile at -O1 or -O3. The fault also exists in gcc-4.6.1. It does not exist in gcc-4.5.3 or trunk r178025. This is in a Cortex-A9+NEON+Thumb-2 configuration.
