[BioC] Rsubread crashes in 32bit linux

Dear Dan,

Thanks a lot for the information. 

The final step of the gcc compilation, which will link all the object files and creates the dynamic library Rsubread.so, should not have a large consumption of the memory and should be done fairly quick. So there seems to a problem with this step. Which Linux distribution are you running on your laptop?

Would you please install a C version of the subread aligner onto your laptop? This will be able to figure out it is C or R which caused the problem. The C version can be downloaded from http://subread.sourceforge.net

Thanks,
Wei
