I find it hard to believe that Khaled has not taken an interest in this particular problem. The bug exists. It should not exist. And only quiet from the developer.
I have 2 scripts that are totally broken by this problem. Thus far, efforts to replace the write process with fwrite results in errors to the test file being written to.
Come on folks.. if you want folks to switch to 6.12 and avoid the exploits present in previous versions, then fix this problem so they can!
This problem is easily duplicated. For scripts that need to do any appreciable amount of writing to files.. FAILURE! At least give us news on whether we should expect a fix.
