ssc::RunSet has only one constructor, which takes no parameters.

#include"Executive.h"

void ssc::Executive( int argc, const char* args[] ){ ... ssc::RunSet runset; /* FAILS HERE */ runset.run(); }

You should also provide the code of RunSet, at least the relevant parts, otherwise it's hard to see why the constructor fails. Philipp

OK, that itself is helpful. I'd forgotten to look in the most obvious place (and forgotten to switch of optimisation before debugging ;-( ) When constructing RunSet on the stack, I get a segmentation fault during dynamic_cast in setStream(). I don't understand that one at all. I can work around this one, but I'd really like to know what's going on here in case there's a more subtle bug lurking. Does anyone know what "warning: can't find class named `ssc::RunSet', as given by C++ RTTI" means? (See debug info below) RunSet::RunSet(){ result = new Result( stream ); result->setShowIntroduction( true ); result->setShowOutput( true ); result->setShowSummary( true ); setStream( &std::cout, "output" ); algorithm = 0; multipleRuns = 0; upperBounds = 0; lowerBounds = 0; resultType = BEST; } void RunSet::setStream( std::ostream* stream, const std::string stream_name ){ if( dynamic_caststd::ofstream*( this->stream ) ) delete this->stream; this->stream = stream; /* propagate to result and algorithm->result */ result->setStream( this->stream ); if( algorithm != 0 ) algorithm->setStream( this->stream ); this->stream_name = std::string( stream_name ); } Program received signal SIGSEGV, Segmentation fault. 0x4029834f in __dynamic_cast () from /usr/lib/libstdc++.so.5 (gdb) #1 0x080768c4 in ssc::RunSet::setStream(std::ostream*, std::string) ( this=0xbffff3e0, stream=0x80ab0f8, stream_name= {static npos = 4294967295, _M_dataplus = { = {<No data fields>}, _M_p = 0x80ad4a4 "output"}, static _S_empty_rep_storage = {0, 0, 1, 0}}) at RunSet.cc:144 (gdb) print this $1 = (RunSet * const) 0xbffff3e0 (gdb) print this->stream warning: can't find class named `ssc::RunSet', as given by C++ RTTI $2 = (ostream *) 0xbffff420 (gdb) print algorithm warning: can't find class named `ssc::RunSet', as given by C++ RTTI $3 = (class Algorithm *) 0xbffff5c4 (gdb) -- JDL Non enim propter gloriam, diuicias aut honores pugnamus set propter libertatem solummodo quam Nemo bonus nisi simul cum vita amittit.
