Hi

based on LTP version 20210524-184-g18800c0de, found a LTP syscalls mmap18 segfault in both 32-bit and 64-bit binary, in the same 64-bit OS setup, Linux Kernel version v5.13.

32-bit mmap18 segfault info: mmap18[32160]: segfault at f7dbbffc ip 000000000804aae3 sp 00000000f7dbc000 error 6 in mmap18[8048000+26000] mmap18[32162]: segfault at f7dafffc ip 000000000804aae3 sp 00000000f7db0000 error 6 in mmap18[8048000+26000]

64-bit mmap18 segfault info: mmap18[91645]: segfault at 7f609099aff8 ip 0000000000403c96 sp 00007f609099b000 error 6 in mmap18[400000+24000] mmap18[91647]: segfault at 7f609098eff8 ip 0000000000403c96 sp 00007f609098f000 error 6 in mmap18[400000+24000]

is there anything unexpected by LTP test? or anything might need to fix here?

Same here, the segfault is expected and it's easy to figure it out from the test source code.
