I thought so. Unfortunately, this is true only in SOME systems I believe. My application was compiled with: -pedantic -static -m64 -O3 The binary works in many machines but the one I got problem with. It even runs a portion of the program but then throws the exception as shown in the title. The machine in trouble got: Linux xxx.xxx.xxx 2.6.18-164.6.1.el5 #1 SMP Tue Nov 3 16:12:36 EST 2009 x86_64 x86_64 x86_64 GNU/Linux the output of g++ --version: g++ (GCC) 4.1.2 20080704 (Red Hat 4.1.2-46) Please take a look at this because it stops my binary from proceeding. THANK YOU SO MUCH Beman! " Bugs closed To Be Determined filesystem Boost 1.47.0 Showstopper fixed
