s4:registry - "patchfile_dotreg.c" - fix a memory leak
Here we allocate memory on the "NULL" context through "reg_val_data_string" on each call of "set_value". So when we have written out the allocated data on the specified file descriptor we should immediately free this memory! Otherwise we may end up with a big memory consumption on big registry databases.
