on windows 2000, notepad runs fine, but not calc:

% bin/drmemory.exe -dr_debug -debug -- calc
:::Dr.Memory::: Dr. Memory version 1.4.1
:::Dr.Memory::: options are "-logdir `c:\derek\DrMemory-Windows-1.4.1-1/drmemory/logs` -resfile 976 "
:::Dr.Memory::: log dir is c:\derek\DrMemory-Windows-1.4.1-1/drmemory/logs/DrMemory-calc.exe.976.000
:::Dr.Memory::: ASSERT FAILURE (thread 1048): ....\withwiki\trunk\common\alloc.c:1808: ALIGN_BACKWARD(start, 64*1024) != (ptr_uint_t) get_private_heap_handle() (app using priv heap)
