Please don't report on very old and unsupported versions like 2.6.4. This bug has been fixed some time ago. I tested it with fixes and trunk. |

He did mention it was te same in 3.0.0 (in field "Product Build", but he should have put 3.0.0 in "Product Version"). |
|
|
As an aside: A small addition to the web interface can warn users that they are reporting on old versions. That can still be relevant of course, but better to stimulate the user to test on a supported version first. @Bart: can you confirm it for the RC? I can't under linux debian. |

I have. I ran this program with fpc 3.1.1 builded from commit #3a9177a. No any exceptions. Just a new line in output. |
|
|
Is the issue present in the 3.0.2RC1 version? |
|
|
I've added an explicit check for Nil in AnsiExtractDequotedString. The TypeCast in AnsiDequotedString does seem fishy, though. |
