valgrind suppressions for current CVS Guile

valgrind suppressions for current CVS Guile

[Bill Schottstaedt]

On the very slight chance this might save someone else
some time, here are the valgrind suppressions for the
current guile (valgrind's memcheck tool is very unhappy
with guile):

{
    scm-1
    Memcheck:Cond
    fun:scm_i_find_heap_segment_containing_object
    fun:*
}
{
    scm-2
    Memcheck:Cond
    fun:scm_gc_mark
    fun:*
}

{
    scm-3
    Memcheck:Cond
    fun:scm_mark_locations
    fun:*
}

    Memcheck:Value4
    fun:scm_gc_mark

    fun:scm_from_locale_string
    fun:*

{
    scm-19
    Memcheck:Addr1
    fun:memcpy
    fun:scm_from_locale_stringn
    fun:scm_from_locale_string
    fun:*
}

{

Thanks!

"Upon further review", I think these were not Guile problems after all.

Valgrind does report a minor memory leak, which I forgot to bring in
to work -- it was in scm_strftime in stime.c, calling bdtime2c (line 641),
which calls scm_to_locale_string (line 541) to fill a field of a struct ("t")
that is inaccessible upon exiting the function. I can get the exact
messages if you need them.

Thanks, I applied a fix.

(scm_strftime probably should be using a frame for its memory stuff,
but that can wait.)
