GUILE does conservative garbage collection, which entails scanning
(possibly uninitialized) chunks of memory for possible pointers. The
valgrind errors are harmless.

Here's a suppression file for 1.6 and for 1.7 CVS

****************
1.6:

{
guilegc
Cond
fun:heap_segment
}

{
guilegc
Value4
fun:scm_mark_weak_vector_spines 
}
{
guilegc
Cond
fun:scm_mark_weak_vector_spines 
}

{
guilegc
Value4
fun:scm_scan_weak_vectors 
}

{
guilegc
Cond
fun:scm_scan_weak_vectors 
}

{
guilegc
Value4
fun:scm_gc_mark
}
{
guilegc
Cond
fun:scm_gc_mark
}

{
guilegc
Cond
fun:scm_gc_sweep
}

{
guilegc
Value4
fun:scm_markstream
}


{
guilegc
Cond
fun:scm_mark_locations
}


{
guilegc
Value4
fun:scm_markcdr
}



****************

guile 1.7 and later

# guile valgrind suppression file
{
    guilegc
        Value4

{

    guilegc         
        Value4
    fun:scm_gc_mark
}

{
guilegc

}

{
