She pointed PC-lint Plus SE at the flight control module’s core file: nav_sensor.c .

“Can we keep the license?”

The drone stayed stable. On Friday, Eleanor presented the root cause to the client. Hank sat in the back, arms crossed, smiling faintly. After the meeting, Eleanor walked to his desk. pc-lint plus se

She fixed the loop by adding a restrict qualifier and a bounds check on offset . Recompiled. Ran the hardware-in-the-loop test. Seventeen hours passed. Twenty. Thirty. She pointed PC-lint Plus SE at the flight

nav_sensor.c(412): error 4150: (Severe -- Semantic dataflow) Pointer 'temp_ptr' derived from 'sensor_buffer + offset' where offset is tainted by unvalidated CAN bus input (path: can_rx_handler -> validate_crc -> extract_payload -> compute_offset). Alias set analysis shows 'temp_ptr' and 'calib_ptr' may converge after loop unrolling at line 408, leading to write-write conflict when temperature exceeds 85°C. [Reference: CWE-123, MISRA C:2023 Rule 11.9] Eleanor froze. She scrolled up. The analyzer had traced a data flow across seven functions, through three files, and had identified not just a memory corruption, but the exact temperature threshold where it would manifest. Hank sat in the back, arms crossed, smiling faintly

“That’s it,” she whispered.

“We can’t. But we also can’t afford a drone that falls out of the sky. I’ll pull strings.” Two hours later, a license file landed in her inbox. Eleanor downloaded the tool, a command-line beast with no GUI, just a configuration file that looked like an ancient spellbook. She spent the next hour tuning it: setting the dialect to C17, enabling MISRA C:2023, turning on the aggressive interprocedural analysis, and—her final gambit—flipping on .
