When I run "./soplex -s1 -e -m45000 pds-50.mps" Seg fault is:

When I compiled spxweightst.cc and spxsolve.cc by old compiler I received Sef
fault in other place. It seems to me that the problem in header files, maybe
svector.h is compiled incorrectly.

The miscompiled file appears to be spxweightst.o, the miscompilation probably
happens when transforming a call to int soplex::DataSet<DATA>::number(const
soplex::DataKey&) const [with DATA = soplex::SVSet::DLPSV]
