--- Comment #8 from Martin Liška <marxin at gcc dot gnu.org> ---
I tried reducing that to:
$ cat set_memory.i
enum { CPA_PROTECT, CPA_DETECT } check_conflict(int warnlvl, long) {
warnlvl || conflicts();
}
long static_protections_start;
static_protections(warnlvl) {
check_conflict(warnlvl, static_protections_start);
lookup_address_in_pgd(0, static_protections_start);
}
__change_page_attr_numpages;
__change_page_attr() {
__change_page_attr_numpages = 2;
static_protections(CPA_DETECT);
}
$ gcc set_memory.i -w -g -O2 -c && llvm-dwarfdump -c
--name="static_protections" set_memory.o | grep "0x0000000000000055,
0x0000000000000055"
[0x0000000000000055, 0x0000000000000055): DW_OP_reg4
RSI)
Is it an example of the error you reported?
