The reference '&' is missing in the function parameter. If there are back-to-back optimizations in terms of dag node list like below: t29: i64,ch = load<LD4[bitcast (%struct.test_t* @test.t to i8*)+12](dereferenceable), zext from i32> t3, t43, undef:i64 t34: i64,ch = load<LD4[bitcast (%struct.test_t* @test.t to i8*)](dereferenceable), zext from i32> t3, t41, undef:i64 The bug will trigger a segfault for the added test case remove_truncate_5.ll: LLVMSymbolizer: error reading file: No such file or directory #0 0x000000000241c4d9 (llc+0x241c4d9) #1 0x000000000241c56a (llc+0x241c56a) #2 0x000000000241aa50 (llc+0x241aa50) ... #22 0x0000000000fd5edf (llc+0xfd5edf) #23 0x00007f0fe03bec05 __libc_start_main (/lib64/libc.so.6+0x21c05) #24 0x0000000000fd3e69 (llc+0xfd3e69) ...
