Just for the record: It was not TProcess and also not the streams, at least not directly: After further experimenting and simplifying the dll until it finally consisted of nothing more than only two functions that would create and destroy some dummy object without any functionality I still saw this exception immediately when freeing the object and the same exception again *after* the host app had unloaded my dll. I have now put the cmem unit into my uses (I always only saw this mentioned in combination with the cthreads for *ix, never thought that it was usable on win32 too) and the exceptions while freeing obects seem to have all gone away. However I still see exactly one such exception *after* unloading the dll but the host app seems to be able to catch it without crashing. (the host app is unfortunately a commercial closed source application and probably written in C++ [at least it is definitely not from any borland or compatible compiler since FPU exceptions are masked]) Bernd _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
