{ Simple test of 4 string comparison routines: [Ansi]Compare(Str|Text)
|
|
with AnsiStrings with #0 chars inside.
|
|
|
|
FPC 1.9.5 fails only at CompareStr + ('hello', 'hello'#0'bye')
|
|
test, passes all other.
|
|
After applying my small patch to sysstr.inc, FPC 1.9.5 passes
|
|
all tests.
|
|
|
|
Delphi note: Kylix 3 does not pass this test with Ansi- functions,
|
|
it seems that in Kylix 3 Ansi- functions consider #0 char to mark
|
|
end of AnsiString (I will not submit this as a compatibility bug,
|
|
as I consider this stupid, FPC behaviour is definitely more
|
|
sensible and consequent here).
