A bug in the Microsoft Visual C++ 4.0 compiler??
I was having some problems with Franci: she crashed in the malloc routine. [I.e., it entered and did not reemerge]. This is often caused by the abuse of free and/or realloc on pointers that were not directly created by malloc. However, the Microsoft C memory management library does not provide real-time detection of these problems.

My response was to write a replacement library that implemented the following functions

The replacement library immediately diagnosed my problem as an inappropriate realloc. However, some features of the startup code before the program started had to be dealt with.

October 1, 1999: Figured out (this is not mentioned explicitly where it should be in the MS C++ 4.0 documentation) that when using the Win__ OS function VirtualAlloc, the memory-access flags are also required for reserving virtual memory, as well as actually committing it. After some code fixing, the memory manager is now at alpha version 0.02.

March 23, 2000: Somewhere along the line, I altered the memory manager enough to get it to version 0.03. I started porting Franci to Borland C++; this port is apparently completed. Borland's V5.5 startup libraries do not require the bypass.
