Package: sccache Version: 0.9.0-1 I am currently looking at updating rust-backtrace and related packages to the latest version, backtrace itself is not semver-breaking but a number of it's dependencies are.
backtrace 0.3.69 -> 0.3.74 addr2line 0.21.4 -> 0.24.2 object 0.32.3 -> 0.36.5 gimli 0.28.1 -> 0.31.1 ruzstd 0.5.0 -> 0.7.3 sccache in particular depends on rust-object. After bumping the dependency I got a failure to find macho::FatHeader::parse , checking the upstream changelog I found the following entry. Replaced macho::FatHeader::parse, macho::FatHeader::parse_arch32, and macho::FatHeader::parse_arch64 with read::macho::MachOFatFile, read::macho::MachOFatFile32 and read::macho::MachOFatFile64. #623 After doing some exploration of the new API there doesn't seem to be a way to try to parse a FatHeader without knowing before hand if it is the 32 or 64 bit version. So I made the code try both one after the other (and if both fail, it assumes it's not a fat binary). After applying the patch, I got the same number of test failures as reported in bug 1090040
