OO1.1.2 + current debugging info on "junk pointer, too high"

[Poul-Henning Kamp]

I ran a ktrace with the phkmalloc utrace code activated
and found the "pointer" it complains about:

 60796 setup.bin CALL  utrace(0xbfacb680,0xc)
 60796 setup.bin USER  12  00 d0 0f 08 00 00 00 00 00 08 00 00

                           ^^^^^^^^^^^
this corresponds to ascii "n_US" and is clearly not a pointer.


This happens in a child process which is most likely trying to
execute the gnomeint program as the fork happens right after
this (slightly bogus) lookup sequence:

 60726 setup.bin NAMI  "/sbin//usr/local/OpenOffice.org1.1.2/program/gnomeint"
 60726 setup.bin NAMI  "/usr/sbin//usr/local/OpenOffice.org1.1.2/program/gnomeint"
 60726 setup.bin NAMI  "/bin//usr/local/OpenOffice.org1.1.2/program/gnomeint"
 60726 setup.bin NAMI  "/usr/bin//usr/local/OpenOffice.org1.1.2/program/gnomeint"
 60726 setup.bin NAMI  "/usr/local/bin//usr/local/OpenOffice.org1.1.2/program/gnomeint"
 60726 setup.bin NAMI  "/usr/X11R6/bin//usr/local/OpenOffice.org1.1.2/program/gnomeint"
 60726 setup.bin NAMI  "/home/phk/bin//usr/local/OpenOffice.org1.1.2/program/gnomeint"
 60726 setup.bin NAMI  "/usr/local/OpenOffice.org1.1.0/program//usr/local/OpenOffice.org1.1.2/program/gnomeint
"


What will it take to get this problem fixed ?
