[DUG] StrCopy problem

[Ross Levis]

Doesn't really help.

 

a := 'abcdefghi' does allocate 9 bytes of RAM.  I can access a and b after
it is assigned.  The problem is StrCopy crashes.  I would expect "a" to have
the same string as b once this is executed.

var

  a: pChar;

  b: pChar;

begin

  a := 'abcdefghi';

  b := 'jklmnopqr';

  StrCopy(a,b);

end;

 

Question:  Why does this code crash?
