[R] safest way to subset (and replace) a data.table

I would like to replace a data.table 'DT' with a subset of itself, where
the subset is determined by an expression 'expr' which evaluates to
logical. Thus far I've been using:
DT <- DT[expr, ]
however this frequently results in a SIGABRT from glibc of the form:
"double free or corruption (!prev): 0x00000000c08662b40"
I've tried under the latest version of R and the latest version of data
table, but the issue still persists. So now I'm wondering if I'm doing
it the wrong way.
