I have updated both the operating system and the developer tools. The 
problem seems to be the GCC compiler. It produces very strange code for 
ECL and the version of GDB that is shipped with XCode cannot even cope 
with it: I am debugging one function and it suddenly jumps to a 
different one. That happens even without optimizations, i.e. "-O0". I 
guess it is a too agressive compiler and it might break some implicit 
assumptions in ECL.

In the mean time, you can build ECL using the older compiler which is 
also shipped with XCode, that is GCC 3.3. This has also the advantage 
that the same binary will work on OSX 10.3. The steps are easy, just 
prepend "CC=gcc-3.3" to your invocation of "configure" as in

     CC=gcc-3.3 ./configure --prefix=$HOME

or use the gccselect utility shipped with OSX.

Please report any further problems you find.

Regards
