- Does it still happen with R-2.9.0 alpha?
- If so, can you please send us reproducible code in order to make able
to see the error on our systems?
Best wishes,

Hi, I was wondering if someone in the mailing list has any insight into this
segfault error that I consistently find when running a script containing
heatmap() in R 2.8.1 and 2.8.0 on a Linux 64-bit machine.
Some points:
1. This occurs when running heatmap().
2. Interestingly, if I source() the script or copy and paste the script in
its entirety, this error occurs. However, if I run the commands
individually, heatmap() will actually work.
3. I've had this error occur on two types of machines as follows. Intel
64bit, linux kernel 2.6.18-92.1.22.el5, gcc version 4.1.2 as well as AMD
64bit, linux kernel 2.6.9-5.ELsmp, gcc version 3.4.3
Here is the error messages that I receive when I debug(heatmap) and source()
the script containing heatmap(). The sessionInfo() follows.
