Hello,
my app does http transfers using the Synapse library on Windows and
Mac OS X. The transfers happen in separate threads. On Mac OS X only,
the app is occasionally stopped due to a SIGPIPE.
How can I avoid or handle a SIGPIPE?

Also installing packages into Lazarus caused all kinds of unit conflicts
This usually means that they were compiled by a previous compiler, or
that they use units which have been changed and recompiled since the
previous compilation. In that case, the compiler will ignore the
precompiled unit and try to recompile it. If it then doesn't find the
sources,

Another, more seldom reason for recompilation problems is that you

unit. In that case the compiler thinks that your file is the new source

I am doing a regular heaptrc.DumpHeap now and I see that WideString

immediately?

Unless heaptrc shows leaks when the program exits, no memory leaks
happen.
It's a leak. The program loses hundreds of MBs of memory just by
working with WideStrings. I compared it against FPC 2.2.4 - no leak.
An SVN snapshot of 2.5.1 from around 3 months ago also leaks.
