The test suite was developed with a 32-bit ooRexx. A large number of tests fail on 64-bit ooRexx, mostly because of the difference in the default numeric digits.
This tracker item is opened to co-ordinate the work on improving the test suite to run correctly for both 32-bit and 64-bit.
If you are working on the test cases, just add a comment here as to which ones. Most of the failures are concentrated in a few test group files.
Attached is the log of an initial run of the test suite.
