Potential problem with BOBYQA optimizer
This problem was identified by Xavier Meyer.
The small problem I noticied is in file BranchSiteModel.cpp starting at line 1850 to 1854 :
// --------------------------------
if (mFixedBranchLength)
{
nlopt::opt local_opt(nlopt::LN_BOBYQA, mNumTimes+mNumVariables);
opt->set_local_optimizer(local_opt
}
// --------------------------------
The "mNumTimes" shouldn't be present since branch are fixed in this case. I tried to launch with "-m99 -bl -bf" and it crashed with "Default exception caught." after removing "mNumTimes" it seems to work. Maybe already fixed in latest version.
