We consciously disabled debugging symbols on MSVC 32 bit to avoid spurious Out Of Memory linker errors (commit 7fc3024a16af6e96b6391b0dc19d6b5887372d05). 

The best workaround is to build with MSVC 64 bit :) If you want to nevertheless try to build 32 bit with debugging symbols, you can revert the commit, or just comment out 

	GYP_CONFIG += fastbuild=2

in src/core/config/windows.pri. Then delete .qmake.cache and configure again.



PS: Task for this was https://bugreports.qt.io/browse/QTBUG-49545
