#60 FastMM 4.991 crashes on OS X

[Erik van Bilsen]

FastMM 4.991 crashes on OS X when using the System.RegularExpressions unit that ships with Delphi XE 2.
To reproduce build the attached sample project and run it on OS X. It is basically this routine:

procedure Run;
var
A: TArray<String>;
S: String;
begin
WriteLn('Begin test...');
A := TRegEx.Split('a|b', '|');
for S in A do
WriteLn(S);
WriteLn('End test.');
end;

It runs fine with FastMM 4.98 (on OS X), but with version 4.991 it crashes in the TRegEx.Split method. It seems it crashes on the __pcre_free call in the pcre_dispose routine in the System.RegularExpressionsAPI unit.

Hi Erik,

This is a known bug:

Report No: 106838 Status: Closed
[OSX] RegularExpressions crashes when using FastMM4

It was fixed in XE3.

Best regards,
