[Bioc-devel] Question about cstack usage error

Hi,

We've been encountering a cstack related error on the build systems on 
random occasions 
(https://master.bioconductor.org/checkResults/3.18/bioc-LATEST/ReactomeGSA/nebbiolo2-checksrc.html):

Error: C stack usage  7970308 is too close to the limit

I know, that the limit can be adapted using the "ulimit -s 16384" 
command before starting the R session.

Unfortunately, in our case it seems to be caused by a call to the 
gplots::heatmap.2 function.

Thanks a lot!

Kind regards,
Johannes
