But at least Apple hasn't started "unbundling the compilers" which was 
the fear resulting from the lack of clarification when they started 
charging for XCode 4.  For OS X 10.6, XCode 3 is free, while for OS X 
10.7 XCode 4 is free.

Anyways, as to the problem that started this thread"  XCode 4 makes LLVM 
(aka clang) the default compiler, which I thought might have been the 
problem with ecl-11.1.1, so I compiled with gcc-4.2.1 (available as 
/usr/bin/gcc-4.2 with XCode 4.1 installed), but still get the segfault 
in the ecl-min compilation step, so it doesn't seem to be the compiler.

The core file shows a stack trace for an endless loop from 

#2424 0x000000010f6c4dd3 in GC_clear_stack_inner ()
#2425 0x000000010f6c4dd3 in GC_clear_stack_inner ()
#2426 0x000000010f6c4ee9 in GC_clear_stack ()

"A screaming comes across the sky.  It has happened before, but there
is nothing to compare to it now."
