@wikingpong13:29
mikelingAs to the memory leaking case you said in https://github.com/shogun-toolbox/shogun/pull/3608#discussion-diff-100508822R318, how could I test them locally13:30
mikelingdue to all the tests passed locally13:30
@wikingvalgrind it13:30
@wikingthese are standard stuff13:31
@wikinggoogle can answer you13:31
@wikingit has nothing to do with shogun... it's c/c++ development13:31
@wikingif you cmake with -DBUILD_DASHBOARD_REPORTS=ON ..13:31
@wikingand then run13:32
@wikingctest with -D ExperimentalMemCheck13:32
@wikingyou should get reports13:32
@wikingbut it takes a long time to run it so filter it down to the classes you've touched13:32
mikelingok, I will do it right now. thank you!13:33

@wikingmmm if u debug with release17:44
CaBathe dylib debug build seems to have done what it should do :P17:44
@wikingit's gonna be hard to debug17:44
@wikingas you miss all the debugging text17:45

@wikingsrc17:49
@wikingso like17:49
@wiking <cloned dir>/src17:49
CaBayeah that's the "to" part of the mapping17:50
CaBa"Source path remappings are used to track the change of location between a source file when built, and where it exists on the current system."17:51
CaBamy source has never moved17:51
CaBait's still right where it used to be during the build17:51
CaBamaybe it's though missing debug symbols... maybe the dynamic linker is just picking up the wrong dylib...17:54

CaBawiking: are there any issues with ccache i could run into when building shogun in debug / release mode? like cache hits that shouldn't be?18:06
@wikingnpu18:06
CaBabut i'm anyways quite sure i did a 'ccache -C' before building in Debug mode...18:06
@wikingmmm18:06
@wikinglemme look into it18:06
CaBawiking: this really seems to be an issue of missing symbols... i don't even see the file:line in the bt output18:06
@wikingotool -Vd18:07
@wiking?18:07
CaBawiking: which i guess should be seen in the backtrace even if he wouldn't know where the file is18:07
