another memory corruption case
Summary
A detailed narrative of memory corruption observed during system builds after updating GCC. The author traces intermittent ggc/SIGSEGV crashes to potential hardware (DRAM) faults, describes memtester and memtest checks, and documents a workaround using kernel memmap to quarantine a faulty RAM region. The piece argues that software bugs are less likely and stresses RAM reliability and robust testing for reproducible builds.
