 Hi

 I have compiled symphony with openMP.
 I am using CentOS 5 (gcc 4.1.1 with openMP backported by RedHat)

 When running symphony -p 4 -L file.mod -D file.dat the program segfaults
 after 2
 hours. Using gdb I get:


 Program received signal SIGSEGV, Segmentation fault.

 Thank you for the nice work with symphony.
