Segfault in GetNewPage, memory.c.
Hello.
I'm still working on my OCaml-R binding and I get a segfault in the
GetNewPage() function of memory.c.
For the record, the OCaml-R binding seems to work fine with OCaml
bytecode. The segfault here is the main issue I have with OCaml native
code. OCaml-R can be found on the following links.

Trash Plugin bugs
dovecot v2.2.16
I've found a few bugs in Trash plugin.
1. If Quota set only messages limit (without storage limit) then
Trash plugin does not expunge any message because Quota plugin sets too_large_r=TRUE.
It's because quota_default_test_alloc function does not check if bytes_limit is set.

sweave provoked segfault (PR#2809)
This problem is with R 1.7.0 (as released) on Linux and Solaris. Details below
are from Linux, Mandrake 9.1. The problem also happened with R 1.6.2 and on
Mandrake 9.0.

Memory crash
Hello,
I get a segfault when running glmmboot in my own package glmmML. Has
happened many time before, but this time I get no hint of where in my C
functions the error might be. I give the output below. Can this be an R
bug? I suspect it has to do with repeated calls to 'vmmin' like this:
for (...){
vmax = vmaxget();

R 1.6.1: help with debugging error in RunGenCollect(), R_gc_internal
Hi,
[System info: R 1.6.1 compiled from source (no args to configure) on
Redhat 7.1 Linux i/386]
I have some spatial statistics programs that recently (since R 1.6.1)
have generated SIGSEGV. These R programs use the splancs library as
well as some C code of my own for Voronoi analysis.
The program has a big loop to fit various model parameters against a

default min-v/nsize parameters
Hi All,
This is a very important issue. It would be very sad to leave most users
unaware of a free speedup of this size. These options don't appear in the
R --help output. They really should be added there. Additionally, if the
garbage collector is working very hard, might it emit a note about better
setting for these variables?
It's not really my place to comment on design philosophy,

I've been doing a number of similar measurements, and have come to the
same conclusion. R is currently very conservative about memory usage,
and this leads to unnecessarily poor performance on

RODBC Seg Fault
Hi Everyone,
At the end of this email is a transcript of a problem I have found in
RODBC version 2.3-1. It appears that the bug fix in odbcClose for the
memory leak has meant that the garbage collector is falling over when it
tries to free up the extPtr attribute of the RODBC connection pointer.
Any advice on how to fix this?
Thanks for your help,

can't find array overruns (was: help debugging segfaults)
Dear R-devel,
Last week I got several responses to my question about debugging segfaults
in my code (original post below). After I changed the S_alloc() calls to
Calloc()/Free(), the symptom was gone, but I was told to keep looking. So I
did:
o Switched to Calloc/Free. Electric Fence did not find any problem.
o Put assert(index < bound); assert(index >=0); everywhere in the C routine

sshd and consequences of HostKeyAgent

Adding idmap backend = idmap_rid... and possible consequences
I have Linux machine with Samba 3.5.11 working great.
I was using passdb backend = tdbsam
So when I tried to setup a second Linux machine I failed..since UID/GID's
were different
when I copied fiels from server 1 to server 2.
Would you recommend me to use IDMAP_RID with Winbind?
BTW, I don't have domain trusts (which is required to be "off" when using
rid).
