at the crash the high_pc was 0x10222c0c, so I've checked how the binary looked, and it indeed has this strange reversed high/low pc:
bloaty crashes when the high_pc is of a DIE is greater than the low_pc. Also when the high_pc is 0. Both of these happen with GHS arm 2022 compiler

I'm not sure if I can provide a dummy binary that showcases this strange reversed pc for a dwarf tag.
