[Boost-users] follow up on regex questions

Hi,
Thanks for your help in the past. I would  normally drop the issue at this 
point
until I get my build environment cleaned up
(" My build is messed up, I haven't read the documentation. What is wrong
with YOUR library?" LOL).
but I do have one more question which I believe is related to boost regex 
processing.
If someone has a known good regex test program or can point to an obvious 
problem
it may be helpful. Again, this code seems to work with Microsoft's greta
and boost gives identical results on a longer list of SIMPLER regexes so I
reasonably believe that the problem is due to handling of more complicated
expression ( One caveat, to be complete, is that greta did seem to return 
some spurious
results but they are easily filter programmatically, things like negative 
location,
but the plausible ones that I have checked manually are right).
However, on this sequence of regexes (regexi?) I get either an abort OR the 
program hangs
later on non-sensical execution (I know, "Gee, you have a build problem and 
the stack is messed up?").

myboost.cpp114 (GU.*?TACTAAC.{20,40}AG|^)(.*?)(GU.*?TACTAAC.{20,40}AG)
myboost.cpp114 ATG(...)*?(TAG|TAA|TGA)
myboost.cpp114 TATAA.*?ATAAA
myboost.cpp114 (GU.*?TACTAAC.{20,40}AG|^)(.*?)(GU.*?TACTAAC.{20,40}AG)
myboost.cpp114 ATG(...)*?(TAG|TAA|TGA)

( progam hangs in my code or had been core dumping in boost::regex )

I think I removed all the stuff with questionable support related to 
assertions
as discussed before.

Thanks.
