[Lazarus] Thread debugging problem

[Leonardo M. Ramé]

Hi, since updating my Lazarus version from svn (I was using a one month
old version) I'm getting a SIGABRT exception in a thread.

The exception apparently is raised while adding items to a TCollection
that is created in the main thread, then passed as parameter to the
newly created thread. If I comment the line "mycollection.add" the error
disapears.

This is the lazarus log I get when running from command line, hope it
helps find the problem:
