In my QML code I open URL in an external browser like this:

Qt.openUrlExternally(link) 

{{}}

When I compile with Qt 6.5.3 it works fine.

When I compile with Qt 6.6.0 the external web browser opens the link, but my application terminates with exit code 1.

This only happens when I enable the address sanitizer of gcc in CMakeLists.txt like this:

add_compile_options(-fsanitize=address)
add_link_options(-fsanitize=address)

Without the address sanitizer it works fine in Qt 6.6.0

It seems that Qt 6.6.0 causes some conflict with the address sanitizer.

My gcc version is: gcc (Ubuntu 11.4.0-1ubuntu1~22.04) 11.4.0

I create this bug report as follow up from:
