[Bug c++/37592] New: compiler gives up optimizing even on 64bit systems

[peter_foelsche at agilent dot com]

When compiling certain complex calculation files I'm getting the message:

/a/new/scs/glow/d2/pfoelsch/build/opt/linux_x86_64-o/gglib/../../../source_opt/gglib/hicum222/NLM.cpp:
In member function 'void NLM_hicumshxpm::CModel::calcDer(NLM_hicumshxpm*,
double*, CDer<13u, double, const double, CDerHelper>*, CDer<13u, double, const
double, CDerHelper>*) const':
/a/new/scs/glow/d2/pfoelsch/build/opt/linux_x86_64-o/gglib/../../../source_opt/gglib/hicum222/NLM.cpp:1014:

/a/new/scs/glow/d2/pfoelsch/build/opt/linux_x86_64-o/gglib/../../../source_opt/gglib/hicum222/NLM.cpp:1014:

I think giving up optimizing because of memory problems 
should not be done anymore on 64bit systems.
Sorry -- I cannot attach the source code.
