Error: Could not find decmpfs resource in resource fork #35

Closed LubosD closed 8 years ago

LubosD commented 8 years ago

Happens when reading /Xcode.app/Contents/Developer/Platforms/AppleTVSimulator.platform/Developer/SDKs/AppleTVSimulator.sdk/System/Library/Fonts/Core/CourierNewBoldItalic.ttf in Xcode_7.2.dmg.

Sometimes I also see "Short read of resource fork map list":

Appears to be a cache related bug (either caused by the cache or hidden by the cache). Adding a complete read of the resource fork at the beginning of ResourceFork::loadResources() makes the bug go away.
