    NTPSHM clobbers altitude under 2.4 Linux

    + +

    We've had one report (in march 2009) of the NTPSHM feature +clobbering altitude reports, on a Technologic TS-5500 board running a +customized 2.4.34 kernel using a gpsd built with 2.95.3. +When NTPSHM was disabled, altitude was reported correctly.

    + +

    Shared memory was bug-plagued on older Linux kernels; one notorious +symptom of this was that the emulation of System V IPC worked poorly, +and we suspect our corruption bug is another symptom. No such +misbehavior has been reported from our NTPSHM-using developers under +2.6. It is also possible that this is due to some obscure bug in GCC +or elsewhere in Technologic's cross-development toolchain.
