Hi, I can report the following:
The problem with the Buffer overflow remains also with OSProcess. Also with the normal vm (https://get.pharo.org ). Summary: I have buffer overflow crashes with my application on Linux. The same code runs without problems on MacOS and on Windows. I have the same test data/database and do exactly the same. The problem occurs only after calling several times OSProcess/OSSubprocess. This is the reason why I first had a suspicion that OSSubprocess is responsible for the crashes. Can anyone tell me how to proceed to find the reason for the buffer overflow? There is no PharoDebug.log Help is very appreciated! This is the message when terminating: root@Pharo_ubuntu_16:/spf/build# ./pharo Pharo-Productive-SPF.image --no-quit SmalltalkImageInstanceID class>>startUp*** buffer overflow detected ***:
