Description
Hi team, I originally posted this issue in chromium here https://issues.chromium.org/issues/423955484, but I think it may help to put it from the LLVM project as well.
Chrome Version : The code from main branch
OS version : Mac OS 15.5 (24F74), ARM
We find that if we build chromium with is_offcial_build = true enabled, then the generated dSYM file will be malformatted or corrupted, and we can't use the LLDB to debug the core .dmp file with that dSYM.
When using dwarfdump to dump the contents of the dSYM binary, we are going to get lots of errors like below:
.debug_info contents:
