Hi Julian,

Thanks for valgrind!!  It's wonderful.
My box (SuSE Linux 8.0) has a Guile library with lots of
problems.  The attached suppression file pretty much gets
rid of them.  I don't know if they've fixed the issues
after Guile-1.4, so I'm  CC-ing them for their possible
interest.  I'm thinking that this should be incorporated
into the default.supp when the Guile library version is 1.4.

Cheers - Bruce

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
    fun:scm_gc_mark_dependencies
}

{

    guilegc	    
	Value4
    fun:scm_gc_mark
}

{
guilegc
Value4
fun:scm_i_find_heap_segment_containing_object
}

{
guilegc
Cond
fun:scm_i_find_heap_segment_containing_object
}

{
guilegc
Value4
fun:scm_markcdr
}

{
guilegc
Value4
fun:scm_mark_locations	
}

{
guilegc
Cond
fun:scm_mark_locations	
}

{
    guilegc
	Cond
    fun:scm_gc_mark
}


{
    guilegc
