Hello,

For one software I compile with fpc, Avast always complained. But only when compiled for debugging.
That exe was sent to the false positive departement, and it toke about _one mounth_ to have a corrected 
version of the AV. Afterwhat, he never complained even with reworked source code.

Cheers, Ched
