Thanks for your very fast responses.

No, I did not need -lstdc++.   But removing it did not change the behavior.

$ REGEX_LIB=/mnt/60GB/sps_home/play/install/lib/libboost_regex-gcc-d.a

$ g++  -I$REGEX_INC -c sp20.cc  -o sp20.o
$ ./sp20
Segmentation fault

No, this does not work:

$ cat jmTest.cc
#include <locale>
int main()
{
  std::locale l;
  bool b = l("a", "A");
  return b;
}

$ g++  -I$REGEX_INC -c jmTest.cc -o jmTest.o
jmTest.cc: In function 'int main()':
jmTest.cc:5: error: no match for call to '(std::locale) (const char [2], const char [2])'

Or, more to the point:

$ g++  -c jmTest.cc -o jmTest.o
jmTest.cc: In function 'int main()':
jmTest.cc:5: error: no match for call to '(std::locale) (const char [2], const char [2])'

I am not familiar with the locale include, but I gather that this should 
work, and the fact that is does not indicates problems with my 
installation of gcc.  Looks like I need to run the gcc test suite.   If 
I were to guess, it seems like there are multiple versions of this 
include, and perhaps gcc4 is finding the wrong one.  And somehow I 
managed to confuse both linux systems that I installed it on.

If anyone has any further suggestions, I would be happy to hear them, 
but it seems like a compiler issue.

Thanks again,
