[BioC] ReadAffy crashes on mac

[Luo Weijun]

Dear all,
I use BioConductor affy package on a Mac OS X 10.4 machine, ReadAffy crashes R. The same problem has been reported earlier by another user (see http://thread.gmane.org/gmane.science.biology.informatics.conductor/16747), but no solution has been suggested yet. 
Here I show you the error message, session  and debug information for R 2.7.1, but the same problem has been observed under R 2.6.0 (both 32 bit and 64 bit versions). 
Please let me know if you have any ideas/comments/suggestions. Thanks a lot!
Weijun
