overflow in vm range

[NickeZ]

Hello!
Thank you for this very nice tool. When I'm comparing binaries built with different compilers (gcc-8 and gcc-11) I get the following error message:

$ bloaty firmware.11.3-2022.08.elf -d compileunits -- firmware.8-2019-q3.elf
bloaty: Overflow in vm range, vmaddr=276388, vmsize=18446744073709275228

diffing them without compileunits work:

+1 Got same error with StarRocks binary:

bloaty: Overflow in vm range, vmaddr=12465963768561892118, vmsize=5980780305148018688

it's like an integer overflow ?

I'm having this issue too.

$ bloaty *.elf -d compileunits
bloaty: Overflow in vm range, vmaddr=1075541649, vmsize=18446744072634009967

I have attached a small repro, a few MiB in size. Cheers!
