I have tried to first debug ‘guile’ with ‘gdb’. Since it crashes, I don't know to get any backtrace from it. However I have noticed that since ‘gdb’ itself is linked with libguile and suffers from the same problem with LD_LIBRARY_PATH improperly set, but doesn't crash. So I have run the following: --8<---------------cut here---------------start------------->8--- mthl@godel ~/src/guile$ gdb gdb [...] Reading symbols from gdb...(no debugging symbols found)...done.
