libasan bug: pthread_create never returns
Hi all,
We observed that under certain circumstances pthread_create() (libasan
implemention) does not return. The conditions are the following:
- address sanitizer enabled
- main and child thread run on the same CPU (affinity)
- real-time scheduling policy for both threads
- different scheduling priority values (this includes the case
of setting a real-time policy for one of the threads and

anyone using LARS package in R
Hi useR's,
Has anyone used the "Lars" package in R before? If so, is there any tutorial
(not manual) or worked out example online for this R package that one can go
through to figure out how one can use this package with lasso regression?
I appreciate any help I can get in this direction.
Sincerely,
Vishal

OSX 10.5 PowerPC and hang after "Looking for __cxa_throw in stdc++"

Factor and Level Issue
Dear useR's
I have a small basic problem which I am hoping to get some help with. I have
a data frame, testSeq_df, with 1 row and 500 columns. Each column is a
character (a,c,g or t). I want this sequence to have 4 factors (a,c,g,t).
When I try the following:
for(i in 1:500){
if (length(levels(testSeq_df[,i]))==1)
levels(testSeq_df[,i]) <-

symbolic computing example with Ryacas

I am trying to implement the following matlab code with Ryacas :

NPTL problem on Centos 4.4
Not sure where to ask this, I've been googling and not finding much that
is helpful.
At work I've got a multi-threaded program targeted at Linux. It compiles
on RHEL 2.1 and 3, and is targeted at 2.1, 3, and 4. UP until today, the
binary built on 3 has worked fine on 4.
But on RHEL4 update 4 it dies a horrible death in pthread_create. I have
reproduced the problem on Centos 4.4, where I

[LLVMdev] lli -force-interpreter complains about external function
Hi Nick:
Thanks for pointing me to libffi.
Recompile LLVM with libffi does solve the problem of printf.
But it still has other problems:
1) sinf() returns 0 in the interpreter, but returns correct value in JIT
(see hellosin.c)
2) calling pthread_create cause lli to crash in the interpreter mode, but no
problem in JIT (see phello.c).
My questions are:
i) can I call any arbitrary external function

Thanks for the response. Yes, I did study the vignette but did not
understand it fully. Anyway, I have tried once again now. I am happy to say
that I have got what I wanted.
