I wouldn't use GetMem() in case of record pointers just in case a
managed type happens to be in there. Unlike GetMem() New() does
initialize those fields correctly. Alternatively one should use
Initialize(myptr^) after the call to GetMem().
I seem to remember being warned in the old days of Turbo
Pascal not mix use of getmem()/freemem() and
new()/dispose() within a program, due to differences in
the memory allocation strategies. Are there still any
compatibility or efficiency/performance issues with
alternating between these two families, or can the most
simple or appropriate call be used interchangeably? In
other words, now that objects are so much more prevalent in
Pascal code, should getmem() and freemem() be avoided?
