Issue with maftools::gtMarkers memory not mapped

[grantn5]

Describe the issue
There is an issue with gtMarkers and the underlying C code of how the function is executed. This results in an error of

*** caught segfault ***
address (nil), cause 'memory not mapped'

Traceback:
 1: withCallingHandlers(expr, warning = function(w) if (inherits(w,     classes)) tryInvokeRestart("muffleWarning"))
 2: suppressWarnings(invisible(.Call("snpc", b, lfile, mapq, sam_flag,     fa, opcount, PACKAGE = "maftools")))

To make sure I have got all the correct libraries installed with no conflicts I pulled the docker form biocontainers and ran the command within the image

docker pull quay.io/biocontainers/bioconductor-maftools:2.18.0--r43ha9d7317_1

This container does not contain the R.utils library so needs to be installed i then ran the following command

Command
Please post your commands and the output (errors or any unexpected output)

maftools::gtMarkers(t_bam = "my_tumor.bam", ##No test bam so can't make reprex
                             build = "hg38",
                             nthreads = 1, 
                             verbose = TRUE
                            )

Which will give the error.
