bash crashed with SIGABRT in programming_error()

[ghislaingeffroy]

Simply run '!' command and got:

$ !
malloc: .././parse.y:2314: assertion botched
realloc: start and end chunk sizes differ
Aborting...
malloc: .././parse.y:2314: assertion botched
realloc: start and end chunk sizes differ
Aborting...
$

Not sure about the expected behavior, but certainly not a crash.
