Segfault when performing match on POSIXlt object
Hi All, I found a possible unexpected behavior when performing match/%in% on POSIXlt objects, e.g. : d <- as.POSIXlt('2018-01-01') # match(<anything>,<POSIXlt>) --> segfault match(0,d) # consequently also this fails : 0 %in% d REPORTED ERROR ON LINUX: *** caught segfault *** address 0x16dc2, cause 'memory not mapped' Verified on 3.5.0 on linux,

Segfault when performing match on POSIXlt object
...RTED ERROR ON LINUX: *** caught segfault *** address > 0x16dc2, cause 'memory not mapped' > Verified on 3.5.0 on linux, 3.5.1 on Windows. Confirmed (Linux, I think all version >= 3.4.0, but not in R 3.3.3 (or earlier, presumably). Note the segfault happens inspite of the match_transform() utility which explicitly checks for "POSIXlt" and the code comment which says that "POSIXlt" should have been transformed to character, but seems to fail in recent versions of R. > I think this could be a bug, since even if that match > operation makes no sense...
