I have a multipipe application which runs on a SkyWriter under
Irix 4.0.5 and Performer 1.0. When recompiled on an Onyx under
5.1.1 and Performer 1.1 it core dumps when multiple pipes are
used. Dbx reports the following:

Process died at pc 0x47b71c of signal : Bus error
[using memory image in core]
(dbx) where
> 0 pfFree(0x9c9341, 0x9c9328, 0xa88618, 0x9c9341, 0x50005) ["../../../lib/libpr/mall.c":206, 0x47b718]
   1 pfDelDList(0x9c9341, 0x9c9328, 0xa88618, 0x9c9341, 0x1004984c) ["../../../lib/libpr/dlist.c":79, 0x4928ec]

   4 pfConfig(0x9c9341, 0x9c9328, 0xa88618, 0x9c9341, 0x427580) ["../../../lib/libpf/pfProcess.C":817, 0x448520]
   5 main(0x1, 0x7fffaf40, 0xa88618, 0x9c9341, 0x10017c90) ["main.c":387, 0x428b34]

and I sometimes see the following on the command line:

Performer Fatal (4):pfFree() pointer 0x9c9350 not from pfMalloc

Any pointers? Thanx in advance.
