+# - XFLAGS=/DMALLOC_LOG
+# Causes PuTTY to emit a file called putty_mem.log, logging every
+# memory allocation and free, so you can track memory leaks.

+# - XFLAGS=/DMINEFIELD
+# Causes PuTTY to use a custom memory allocator, similar in
+# concept to Electric Fence, in place of regular malloc(). Wastes
+# huge amounts of RAM, but should cause heap-corruption bugs to
+# show up as GPFs at the point of failure rather than appearing
+# later on as second-level damage.
