RE: debugging threads

["Tim Michals" <tcmichals@verizon.net>]

I've narrowed the issue down it to using -static gcc option version shared
libraries
For example:
Ok, this might be a user error, but... I did exactly what you did and yes it
worked.  I'm using the latest and greatest from boost cvs. So mine is in
/usr/local/lib... So using that library and changing the path ...
[tcmichals@localhost examples]$ g++ -o helloworld helloworld.cpp -Wall
-ggdb2 -
pthread -L/usr/local/lib -lboost_thread-gcc41-mt-d
[tcmichals@localhost examples]$ export LD_LIBRARY_PATH=/usr/local/lib

It worked!!!
ok if I do the following:
The program is running.  Exit anyway? (y or n) y
[tcmichals@localhost examples]$ g++ -static -o helloworld helloworld.cpp

Then I try to exit gdb and it locks up... But I thought -static links the
static library?  
well, now atleast I know what the difference is and the issue, but don't
know why.
