Dear Enrico, I am not trying to debug any particular part of ooRexx, everything runs just fine, all tests (including those I have written) pass without errors. What I am going after is a spurious problem:
REXX-ooRexx_5.0.0(MT)_64-bit 6.05 13 Feb 2019 r11755 Searching for test containers./Users/po/workspace/testooRexx.sh: line 37: 4122 Segmentation fault: 11 rexx testOORexx.rex -s -X native_API I have seen it happening on macOS and on Ubuntu, the segmentation fault just when rexx is starting. Running it again it runs just fine. It happens in average every 25-30 times I run the build&test (on Mac but also on Ubuntu) Since I am not familiar with the debugger on Linux this was an excellent opportunity for me to learn about it.
