IMHO there is no way to count on this being the case in any system. 
DOS, for example.  But 99% of the time, if malloc() fails, your program
cannot effectively continue and will have to be terminated.  Of course,
depending on how interactive/user friendly the program is, it can get
more or less detailed in its error messages.  :)

Umm.. yeah.  :)  In fact, DJGPP is a complete 32-bit protected mode port
of GNU C/C++/Pascal and assorted utilities to MS-DOS.  It is perhaps the
single best MS-DOS compiler in existence, producing code that is faster,
cleaner, and smaller than Borland's 32-bit compiler.  For example, id
Software's hit game Quake was written and compiled using DJGPP!
