Hello Martin and everyone,
Thanks. I added -D_RWSTDDEBUG to the Makefile like:
setstr : setstr.o
CC -D_RWSTDDEBUG -mt -g -xdebugformat=stabs -xs -m64 -library=%none
-I/h/goanna/1/a_5.10_m64/c/include -o setstr setstr.o
-L/h/goanna/1/a_5.10_m64/c/lib -R/h/goanna/1/a_5.10_m64/c/lib -lstd15D
setstr.o : setstr.cpp
CC -D_RWSTDDEBUG -mt -g -xdebugformat=stabs -xs -m64 -library=%none
-I/h/goanna/1/a_5.10_m64/c/include -c setstr.cpp
clean:
rm setstr setstr.o
compiled the following tiny program with Sun Studio 12 on Solaris 10u4 with
stdcxx
compiled from subversion as 64 bit 15D:
#include <set>
#include <string>
std::set<std::string> setstr;
int main(int argc, char *argv[])
{
std::copy(argv, argv + argc, std::inserter(setstr, setstr.end()));
return 0;
}
and ran it, unfortunately though it still encounters a sigsegv. So
I tried running it in dbx with Run Time Checking:
