ODR violations were occasionally observed in presubmit test runs. Our investigation revealed that the issue stems from the Python bindings for absl::Status in pybind11_abseil (see the reported issue: pybind/pybind11_abseil#20). Note: We have tested that this change helps by manually increasing the number of iterations in //py/arolla/py_utils:py_utils_test to 10**6.

The issue can manifest itself in multiple ways. One of the most straightforward examples is that returning an
absl::Statuswith a payload from C++ to Python can cause the process to crash (approximately 1 in 50k times; code that reproduces the issue: https://github.com/apronchenkov/pybind11_absl_cord_odr_issue).It appears that the root cause of the issue seems is that
pybind11_abseilincludes statically linked components of Abseil, which may conflict with Abseil usages within the Python extensions.The text was updated successfully, but these errors were encountered:
