Line and file are empty in Qt breadcumbs

SDKs
1

When looking at breadcumbs generated by the release version of my Qt application, the file and line information are not filled properly:

error
{
file: None, 
line: 0
}

When compiled in debug mode, file and line are set correctly.

I tried to force debug information for release buidl with the following line without success:

CONFIG += force_debug_info separate_debug_info
