Angelica Moreira
123bb620d4 Add ASan/UBSan memory safety CI workflow 
Adds a workflow that builds and tests Z3 with AddressSanitizer and
UndefinedBehaviorSanitizer on every push to catch runtime memory errors
and undefined behavior. Runs unit tests, SMT-LIB2 benchmarks, and
regression tests under both sanitizers. Includes a Copilot agentic
workflow to generate summary reports as GitHub Discussions.

Triggered on push (path-filtered to src/) and manual dispatch.

Merge pull request #8805 from Z3Prover/qmbi_crash 
Fix assertion violation in q_mbi diagnostic output
 2026-02-28 11:28:51 -10:00

93ac330864 Fix assertion violation in q_mbi diagnostic output 
The IF_VERBOSE(0,...) block at line 498 in q_mbi.cpp used operator[]
on values2root map which asserts the key exists. When the model
evaluation of the inverted term produces a value not present in the
EUF values2root map, this crashes.

Use find() instead to handle the missing key gracefully, since this
is diagnostic output and the missing key is expected when the model
inversion produces inconsistent results.

Fixes assertion violation from #7027 (obj_hashtable.h line 168/174)
with forall/array/eq2ineq combination.
