Huge minidumps on Apple Silicon

[Jonathan Jones]

Hi folks,

After making a code change in our product (not Crashpad or crash handling), Crashpad is generating minidumps larger than what should be possible from the crashing process ... minidumps well in excess of 1 GB (with indirect memory capture disabled).

Early analysis shows threads having overlapping address ranges, resulting in massive duplication in the minidump.

Has anyone else reported this?  We used to see this only on macOS Intel, but we dropped support for our product on that platform.  This is the first time we are seeing this on Apple Silicon.

Best wishes,

Jonathan Jones
