Hi again, I'm all the way to building octave on my Leopard / Santa Rosa Macbook. It bombs out during the documentation formatting process: making arith.texi from arith.txi /bin/sh: line 1: 79234 Segmentation fault ./munge-texi -d ../../ src/DOCSTRI NGS -d ../../scripts/DOCSTRINGS < arith.txi > arith.texi.t make[3]: *** [arith.texi] Error 139 make[2]: *** [interpreter] Error 2 make[1]: *** [doc] Error 2 make: *** [all] Error 2 Digging around in the munge-texi program (rebuilt with the -g flag) with gdb, I see the following: (gdb) run -d ../../src/DOCSTRINGS -d ../../scripts/DOCSTRINGS < arith.txi > arith.texi.t Starting program: /opt/local/var/macports/build/ _opt_local_var_macports_sources_rsync .macports.org_release_ports_math_octave/work/octave-2.9.9/doc/ interpreter/munge-texi -d ../../src/DOCSTRINGS -d ../../scripts/ DOCSTRINGS < arith.txi > arith.texi.t Reading symbols for shared libraries +++. done Program received signal EXC_BAD_ACCESS, Could not access memory. Reason: 13 at address: 0x00000000 0x8fe18aa2 in __dyld_misaligned_stack_error () Looks like a null pointer dereference. Anyone have any clues about how to get around this one? Eric
