[REG 5.6.1->5.6.2] macdeploy -always-overwrite fails on qml/quick plugins

With latest update to 5.6.2 (from 5.6.1) and 5.7.1 (from 5.7.0) macdeploy command fails on several qml/quick plugins.

Command:
macdeploy "build/packages/App/data" -no-strip -qmldir=res/qml/ -always-overwrite -executable="build/packages/App/data/Contents/MacOS/Application"

Log:
ERROR: "/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/strip: string table not at the end of the file (can't be processed) in file: /Users/user/project/installer/mac/build/packages/App/data/Contents/PlugIns/quick/libqtquick2plugin.dylib\n"

With -no-strip option I get only messages that otool output cannot be parsed:
ERROR: Could not parse otool output: "/Users/user/project/installer/mac/build/packages/App/data/Contents/PlugIns/quick/libqquicklayoutsplugin.dylib:\n"

In both cases plugin files copied to app bundle are corrupted - much smaller than original ones. Of course app package is not working.

It is working correctly on 5.6.1 and 5.7.0. When I copied Qt/5.6/clang_64/qml from version 5.6.1 to version 5.6.2 it was working correctly. Something is wrong with files distributed in Qt/5.6/clang_64/qml in version 5.6.2 an 5.7.1.

I also used macdeploy from 5.6.1 in 5.6.2 and it failed too - it is not a problem with macdeploy tool itself, but with qml/quick plugins.

For now I can revert to 5.6.1 but it looks as quite import issue.
