| Comment | A tentative fix is included in UG-3.9.1-patch8. Please reopen if the bug rears its ugly head somewhere else. |
Description
The sequential UGGrid test (in test-ug.cc) aborts with a failed assertion when compiled and run with a parallel UG. The failure message is
test-ug: ugm.c:1346: UG::INT GetSideIDFromScratchSpecialRule(UG::D3::ELEMENT*, UG::D3::NODE*): Assertion `(((((UINT *)(f))[0]) & (((1<<(3)) - 1) << 18)) >> 18)==HEXAHEDRON' failed.
(the corresponding line actually reads:
assert(TAG(f)==HEXAHEDRON);
)
The backtrace is
