📝 WalkthroughWalkthroughThe assertion macros now accept variadic arguments through a constexpr helper. Related CUDA call sites remove redundant parentheses, and the routing diagnostic is reformatted without changing behavior. ChangesAssertion updates
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to The PR replaces the assertion macro expansion with a helper-based implementation, but an unresolved CUDA compatibility issue may affect device-capable assertion paths when ASSERT_MODE is enabled. Merge should wait for that annotation concern to be resolved or explicitly accepted by the owner. Suggested reviewers: 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

around assert_msg and cuopt_assert in cpp/src/utilities/macros.cuh lines 23-30,
including template commas, assignment expressions, enabled ASSERT_MODE, and
disabled no-evaluation behavior. In
cpp/src/mip_heuristics/feasibility_jump/fj_cpu.cu, add tests for the
unparenthesized bounds assertions at lines 1015-1016, 1220-1221, 1267-1268, and
1496-1497.
- Around line 23-26: Update assert_msg to accept the printf(...) result used by
cuopt_assert in runtime_checks.cu, while preserving the existing message
contract; add an appropriate overload for non-array message arguments or
evaluate printf separately before calling cuopt_assert, without changing
assertion behavior.

Previously, cuopt_assert was defined as
#define cuopt_assert(val, msg) assert(val&& msg), which could cause operator precedence issues by expanding patterns such as this one into:This has been fixed by passing the cuopt_assert args to a C++ function to circumvent macro gotchas altogether.
As a side effect, constructs like
are now valid.
They were previously rejected because the C preprocessor doesn't recognize colons in template parameter lists.
