Description
Problem description
When testing an ASAN (Adress SANitizer) enabled configuration in qtvirtualkeyboard, the backtraces are lacking source code information for code that goes into the dependency submodules, for example qtdeclarative. Here is the log that belongs to this task. The problematic part is this:
PASS : inputpanel::tst_plugin::test_fullScreenModeWordReselection(row 18)

You can see that it's lacking source code information for the submodules it depends on.
Suggestion
Have a "Coin Feature" that I can enable in a configuration, for example "ExtractDependenciesSourceCode", that always extracts the source code of all other submodules, besides the one being tested.
EDIT: An alternative would be to have a script that would install the source code of all modules on demand, and checkout the correct revision. For example
~/coin_util/checkout_source_code.sh
Actually I like this approach more. It would save a lot of overhead and bandwidth involved in transferring the source in the beginning of the workitem.
