Has anyone been able to successfully run/test a Qt based application built with AddressSanitizer enabled on Windows? I have a 64-bit Qt 6.2.4 build that I built from git using MS Visual Studio 2022 (updated in the last couple of weeks). I've tried building our application, as well as a couple Qt example applications (mainwindow and lineedit) using qmake with this in the additional arguments setting for the qmake build step in Creator: QMAKE_CFLAGS+=-fsanitize=address QMAKE_CXXFLAGS+=-fsanitize=address
If I try to run any of these three applications, execution breaks very early on. For example, with mainwindow execution stops at QArrayData::reallocateUnaligned. This is while executing qInitResources_cursors further up in the call stack. When I run the lineedit example the break is in the initialization of harfbuzz. I have tried debug and release builds, I tried building Qt with the same CFLAGS and CXXFLAGS, and I've tried using cl-clang.exe instead of cl.exe as the compiler. All combinations end up hitting a break in execution pretty early, though not always in the same place. Unlike when I've used asan on macOS, I'm not seeing the full sanitizer output in Creator's application output window, so it's not clear to me whether these are legitimate bugs or if something else is going on. Thanks for any advice Adam
