[comp.sys.encore] select

s900387@minyos.xx.rmit.oz.au (Craig Macbride) (05/13/91)

I have been doing some testing of select() calls on a number of machines,
since it has different effects under different circumstances on some boxes.
I have found that a simple select() from 2 named pipes on an Encore running
System V R2.4 causes the Encore to crash. None of the system calls needed to
set this up (open, select) return any errors, and one doesn't need to be root
for this to happen.

Exactly the same code compiles and runs without this effect on other machines
that I've tried. If anyone knows why this might be happening, I would be
interested to know.

Craig,

Please send me a copy of your test case and we will look into the problem.

Thanks,

Craig was kind enough to forward me a copy of his testcase which
ran successfully (several million iterations) on a beta copy of UMAX V R2.4.1.

UMNAX V R2.4.1 is a maintenance release and is scheduled to release in July.
