At this stage I'd recomend you rebuild the regex binaries using whatever
build options you are using: the exception problem is strongly indicating
that there is a binary incompatibity problem somewhere.
Thanks. I'll give that a try as soon as practical and get back to you then.
I probably should update my compiler too.

This hangs ( I thought it may be a repetition problem but reliably
hits on this data/regex combo first pass):
Not for me: it works just fine here, my complete test program is below,
tested with cygwin g++ 3.4.4, and the version of Boost that's downloadable
with cygwin:
g++ -I /usr/include/boost-1_33_1 t.cpp -lboost_regex-gcc-mt
t.cpp:
#include 
#include <iostream>
int main()
{
   try{
      boost::regex e("ATG(...)*?(TAG|TAA|TGA)");
      const char* s =
"GAGATATTCACCTCTCATTGCCTTTTCCAGAGGTTGTTGAACTTAGTGGCCTGAGCATTTTA"
"TCTGCAAAATGACTAGCAATTTTTTTTTAAGTTTCAGGCTTTTTTAATGCCCTAAATACAGTTGATCCATTACCGAGTGT"
"GTTACATGCATAGGAATTTACTGATCTTTTCTTTTCCCCCTAGCTAGTTTTAAAGTTACTGAGCATAACGAGCTTTAAAA"
"ATTCTTCAGAATACAAATAAATGAATAGATAAAAGACTACCTCCATTTGATAAATCATTCAAGAAAAAGAAAAAAAAACT"
"TGAGCAAGCTAAGAAAGTCATTAACAGCCATATTTCTGATGGAACTAATGTxGATACCTACTCAAGCTAxCACTxGAATC"
         "TAATAATCTGTGAGAGAAGAAATGGGAAAAGGTATGAAAGC";
boost::cregex_iterator a(s, s+strlen(s), e), b;
      while(a != b)
      {
         std::cout << *a << std::endl;
         ++a;
      }
   }
   catch(boost::regex_error e)
   {
      std::cout << e.what() << std::endl;
   }
   catch(std::exception e)
   {
      std::cout << e.what() << std::endl;
   }
}
So I still think that you have issues with your binary install, or build
method or something.
At this stage I'd recomend you rebuild the regex binaries using whatever
build options you are using: the exception problem is strongly indicating
that there is a binary incompatibity problem somewhere.
HTH, John.
