in checking whether the symbol needs to be reloaded. The problem goes
away for me if I define min and max in separate files (i.e., create
min.cc and max.cc, each with only one DEFUN_DLD macro) or if I set
ignore_function_time_stamp = "all" (I'm not sure why setting it to
"system" fails, even when the min/max functions are installed in a
"system" directory).
Though ignore_function_time_stamp = "all", I still get mintime consistently
longer then maxtime:
octave:2> [looptime,maxtime,mintime]=mmt(10000)
looptime = 0.046946
maxtime = 0.19471
mintime = 0.22528
octave:3> [looptime,maxtime,mintime]=mmt(10000)
looptime = 0.040380
maxtime = 0.18160
mintime = 22.642
octave:4> ignore_function_time_stamp = "all"
ignore_function_time_stamp = all
octave:5> [looptime,maxtime,mintime]=mmt(10000)
looptime = 0.040041
maxtime = 0.17199
mintime = 0.21179
...
octave:8> [looptime,maxtime,mintime]=mmt(30000)
looptime = 0.10826
maxtime = 0.51337
mintime = 0.61531

looptime = 0.97805
maxtime = 5.1094
mintime = 6.0628
