Hello, We are trying to port a Project around 220.000 Lines of code from Delphi/Kylix to FPC. Primary it runs :-), our main problems were Variant Support (Various conversions behaving not as in Delphi/Kylix). We made an own Variant Manager (to not break the existing one ) which is closer to Delphi, we would like to contribute if we are done with it.
The biggest problem still not solved is a BUG in the heap memory manager wich causes various SIGSEGV in various pieces of code i reported it yesterday as BUG 4189. (http://www.freepascal.org/bugs/showrec.php3?ID=4189) I want to supply additional info: Program test; var s:string; begin setlength(s,3); setlength(s,655360); -> CRASHES WITH SIGSEGV writeln('OK'); end; Compile with: fpc -Sdh test.pas Program crashes under linux and win32 with current SVN 2.1.1 Problem seems to be in: function SysTryResizeMem(var p: pointer; size: ptrint): boolean; We "FIXED" it by changing function to: function SysTryResizeMem(var p: pointer; size: ptrint): boolean; var pcurrsize, oldsize, currsize : ptrint; pcurr : pmemchunk_var; begin SysTryResizeMem := false; exit; <----------- Don't Resize ..... Thanks for the good work, Helmut _______________________________________________ fpc-devel maillist - [email protected] http://lists.freepascal.org/mailman/listinfo/fpc-devel
