I wrote a test for it and it's only true for 64-bit applications. 32-bit
applications are aligned to 8 bytes. Checked with msvcr80.dll and msvcr90.dll.

The problem may be somewhere else or may be related to stack state after dll
initialization.

A very simple tests that allocates 16-bytes blocks outputs (with native dll,
32-bit application):
malloc(16): 00523810
malloc(16): 00524830
malloc(16): 00524848

And with builtin msvcr80.dll:
malloc(16): 00411428
malloc(16): 00411440
malloc(16): 00411458
