I can't figure out what's going on, but I'm pretty sure I haven't messed anything up during compilation. This is simply running the actual xemacs binary from the src directory. Below is the output from GDB. --- snip --- Starting program: /private/Network/Servers/tcjenkins.bph.jhu.edu/Users/nfitzke1/Software/src/xemacs-21.4.17/ src/xemacs Reading symbols for shared libraries .+.... done Program received signal EXC_BAD_ACCESS, Could not access memory.
