I saw it again on a system by running two parallel build jobs:
D=/tmp/perf-1; mkdir -p $D; while make O=$D install; do make O=$D clean; done
D=/tmp/perf-2; mkdir -p $D; while make O=$D install; do make O=$D clean; done
one failed with:
BUILD PLUGIN plugin_kmem.so
make[2]: *** [sub-make] Error 2
make[1]: *** [/tmp/perf-1/libtraceevent.a] Error 2
make[1]: *** Waiting for unfinished jobs....
BUILD PLUGIN plugin_kvm.so
the other with:
CC FPIC plugin_cfg80211.o
CC /tmp/perf-2/builtin-help.o
CC /tmp/perf-2/builtin-sched.o
plugin_sched_switch.o: file not recognized: File truncated
collect2: error: ld returned 1 exit status
make[3]: *** [plugin_sched_switch.so] Error 1 BUILD PLUGIN
plugin_function.so
and that's clearly the new plugin code.
Thanks,
Ingo
