I can reproduce this locally with an allmodconfig build. The offset parameter to make_nop_arm64 is nuts: Program received signal SIGSEGV, Segmentation fault. make_nop_arm64 (map=0x7ffff7fef000, offset=2600547309829750784) at scripts/recordmcount.c:170 170 if (*ptr != 0x94000000) Both shdr->sh_offset (0x17000000000000) and relp->r_offset (0x2400000000000000) look dodgy in the caller.
