Hi, On two seperate Solaris 8 multi-processor machines (with sufficient RAM and swap space), the final archive command to create the library for reading/writing the dot format crashes with a segmentation fault: OBJS = graphviz_graph_lex.o graphviz_digraph_lex.o graphviz_digraph_parser.o graphviz_graph_parser.o libbgl-viz.a: $(OBJS) $(AR) -rc libbgl-viz.a $(OBJS) When I ran the 'ar -rc ..' command again prefixed with the 'truss' command, it crashed soon after loading the last .o file. Oddly enough, the archive command worked on a multi-processor Linux machine... Any diagnostics as to why the archive command doesn't work on the Solaris machines? Regards Rajesh
