getting error while trying to make dendogram based on gene expression

I am trying to make dendogram based on gene expression matrix , but getting
some error:

I
countMatrix = read.table("count.row.txt",header=T,sep='\t',check.names=F)

colnames(countMatrix)

count_matrix <- countMatrix[,-1]                   #  remove first column
(gene names)
rownames(count_matrix) <- countMatrix[,1]     #added first column gene
names as rownames)

nonzero_row <- count_matrix[rowSums(count_matrix) > 0, # removed row sum

0 across all sample

x1= as.matrix(nonzero_row)                    # converted data into matrix

x=log2(x1+1)                                          # converted into

log value

d <- dist(x, method="euclidean")

h <- hclust(d, method="complete")

*Error:*

 *** caught segfault ***
address 0x7fa39060af28, cause 'memory not mapped'

Traceback:
 1: hclust(d, method = "complete")

Possible actions:
1: abort (with core dump, if enabled)
2: normal R exit
3: exit R without saving workspace
4: exit R saving workspace
