+Summary: We are using strncpy on overlapping strings
+
+valgrind yells at me for:
+
+==21825== Source and destination overlap in strncpy(0x34E0AA89, 0x34E0AA8A, 8)
+==21825==    at 0x3414B90C: strncpy (in
+/usr/lib/valgrind/vgpreload_addrcheck.so)
+==21825==    by 0x80F35AB: canonicalize_path (image.c:108)
+==21825==    by 0x80F4CEA: mono_image_open (image.c:894)
+==21825==    by 0x80ED5EA: do_mono_assembly_open (assembly.c:625)

+==21825== Source and destination overlap in strncpy(0x34E0B782, 0x34E0B783, 8)
+==21825==    at 0x3414B90C: strncpy (in
+/usr/lib/valgrind/vgpreload_addrcheck.so)

+==21825==    by 0x80F4D5C: mono_image_open (image.c:913)
+
+According to the strncpy manpage, the two strings can't be overlapping.
