[Bug c++/21864] New: ICE on invalid command line

[cheinan at atg dot com]

Having a directory name, a -c and -o on the command line causes an ICE and a seg
fault.  The actual code does not seem to matter.  Reproduction instructions and
actual output follow:

cheinan/test> cat null.cpp
int main()
{
   return 0;
}
cheinan/test> g++ /home/cheinan/test -c null.cpp -o MakeMeICE.o
g++: /home/cheinan/test: linker input file unused because linking not done
cc1plus: /home/cheinan/test: No such file or directory
cc1plus: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.
cheinan/test> gcc -v

Workaround:  Fix make file so invalid compiler command lines are not produced.
