I could reproduce this issue in gcc-7.4, but not with gcc-8.2, as can be seen below. Will have to check if this issue is showing up in any other functions. odcphy-vg-1294> module load gcc/7.4.0 odcphy-vg-1294> ./reproduce.csh 000002f0 0000000000000044 000002f4 FDE cie=00000000 pc=0000000000006570..000000000000680a LOC CFA rbx rbp r12 r13 r14 r15 ra 0000000000006570 rsp+8 u u u u u u c-8 0000000000006575 r10+0 u u u u u u c-8 000000000000657e r10+0 u exp u u u u c-8 0000000000006589 r10+0 u exp exp exp exp exp c-8 000000000000658e exp u exp exp exp exp exp c-8 0000000000006592 exp exp exp exp exp exp exp c-8 00000000000065f5 r10+0 exp exp exp exp exp exp c-8 0000000000006602 rsp+8 exp exp exp exp exp exp c-8 0000000000006608 exp exp exp exp exp exp exp c-8 odcphy-vg-1294> odcphy-vg-1294> module load gcc/8.2.0 odcphy-vg-1294> ./reproduce.csh 000002c8 0000000000000034 000002cc FDE cie=00000000 pc=0000000000006450..000000000000676f LOC CFA rbx rbp r12 r13 r14 r15 ra 0000000000006450 rsp+8 u u u u u u c-8 0000000000006451 rsp+16 u c-16 u u u u c-8 0000000000006454 rbp+16 u c-16 u u u u c-8 000000000000645a rbp+16 u c-16 u c-40 c-32 c-24 c-8 000000000000645f rbp+16 u c-16 c-48 c-40 c-32 c-24 c-8 0000000000006463 rbp+16 c-56 c-16 c-48 c-40 c-32 c-24 c-8 0000000000006518 rsp+8 c-56 c-16 c-48 c-40 c-32 c-24 c-8 0000000000006520 rbp+16 c-56 c-16 c-48 c-40 c-32 c-24 c-8 0000000000006550 rsp+8 c-56 c-16 c-48 c-40 c-32 c-24 c-8 odcphy-vg-1294>
