I can confirm this problem (Ubuntu 6.10, gcc 4.1.2) and that -fno-stack-protector does not fix it. A temporary workaround is to use an older gcc for compiling OTcl, TclCL, and ns: export CC="gcc-4.0" export CXX="g++-4.0" (Make sure the above is entered before building OTcl, TclCL, and ns.) In addition, I have discovered that OTcl 1.18 also fails to compile (same error) on my dual-core P4 system with Ubuntu's gcc 4.1.2 and when make is run with the command-line argument "-j 3" (or higher). It compiles without any errors if run without -j or if I switch to gc 4.0.4. I hope this helps someone. Richard
