x86 OrcJIT test error #1003

Closed gmarkall closed 1 year ago

gmarkall commented 1 year ago

In some cases the OrcJIT tests can fail with:

running run_test.py

(spotted during a build of the conda-forge llvmlite 0.41.0 package). I haven't time to look into this, but I suspect that the test test_lookup_current_process_symbol_fails failing to find the symbol messes up / corrupts state somehow, such that even after enabling search for symbols in the current process, lookups still fail.

See also #1002.

This is because it was running on PyPy, where the function Py_GetVersion() does not exist.
