Hi there,

I encountered a significant memory leak when using GDO (base 1.0.1).
Even
for very simple programs, both client and server consume more and more
memory on every transaction (the server side seems to be more affected
by
this problem).
Below you can find some simple source code for demonstration.

Is this a bug or am I doing something wrong? Any help is highly
appreciated.

Is this a problem for you in 1.0.2?

It doesn't seem to happen on my system.

I *did* turn off caching of port coders by default between those two
versions -
perhaps there was a bug in the caching code?


I've checked the simple example with 1.0.2. Although memory growing
seems not to be as rapid as before, both sides still comsume more and
more memory. The server starts with 2.4MB (top), reaching more than
10MB after some minutes (client running).

If this problem doesn't occur on your system, what's the trick?
I'm using gcc 2.95.2, ffcall-1.8a, make-1.0.1, objc-1.0.1,
base-1.0.2 compiled with
    LIBS=-posix; ./configure --prefix=/usr/local/GNUstep
    make shared=yes debug=no install

I left the client and server running for hours - without any measurable memory leak.

I'm running using gcc-3.0, with make and base from CVS

I'm not using ffcall on my system ... I'll look there for possible leaks.
