believe the problem may have something to do with the way the latest gcc (4.4.1) handles symbols in the latest ASL. I created a virtual machine with Ubuntu 8.10 LTS, and used gcc 4.2.4 to compile the IPOPT source with the latest ASL, and it worked like a charm. I copied the compiled binary back to my Ubuntu 9.04 machine (gcc 4.4.1) and IPOPT did not segfault anymore. <br class="" style=""></div><div class="" style=""><br class="" style=""></div><div class="" style="">..."</div><div class="" style=""><br class="" style=""></div><div class="" style=""><div id="yiv5534119644yui_3_16_0_1_1412461463502_11946" class="" style="background-color: transparent;">Here is info on my compiler version:</div><div class="" style="">g++ --version</div><div class="" style="">Configured with: --prefix=/Library/Developer/CommandLineTools/usr --with-gxx-include-dir=/usr/include/c++/4.2.1</div><div class="" style="">Apple LLVM version 6.0 (clang-600.0.51) (based on LLVM
