I compiled LazReport just yesterday and didn't get any internal errors. Remember, such errors are always bugs in FPC. You forgot to mention your FPC version. The code your patch affects has been there forever. Clearly this is not a bug in LazReport. |

The issue is with SysUtils' Trim(variant). The cause was introduced in FPC rev 47111. To reproduce: program Project1; {$R *.res} uses sysutils; var aValue: variant; s: String; begin s := Trim( aValue ); end; end. |

Looks like I've added that aggressive internal check, so I'll have a look at it. What I can actually say about it so far is that the implemented test-condition doesn't match the intended behaviour according to it's comments, so it's probably easy to fix. Thanks for reporting. |
