Re: memory leak? ref: merge test 4

I think the memory usage might actually be our test harness attempting
to read all of the (stderr) output into memory. Thousands and
thousands of lines that read:

svn(56985,0xa0634720) malloc: *** error for object 0x817a00: double free
*** set a breakpoint in malloc_error_break to debug

So maybe svn isn't consuming memory, but is simply generating a
hojillion of these error lines. I forced an abort/coredump, and found
this stack:

#0 0x952e329a in write$NOCANCEL$UNIX2003 ()
#1 0x9538f3ce in malloc_destroy_zone ()
#2 0x9538e8e3 in malloc_zone_print_ptr_info ()
#3 0x9538e943 in malloc_printf ()
#4 0x9538941a in scandir$INODE64 ()
#5 0x952b3523 in malloc_zone_free ()
#6 0x952b338d in free ()
#7 0x004d230c in apr_allocator_destroy (allocator=0x502010) at
memory/unix/apr_pools.c:134
#8 0x000101b5 in main (argc=11, argv=0xbffff0ac) at subversion/svn/main.c:2288

Any ideas?

Cheers,
