`local array` at top-level crashes gnuplot silently
Confirmed. Still happens with 6.0.5 and is not specific to Windows. Of course "local" on top-level makes little sense, but gnuplot certainly should not crash. The code segfaults here: /* Create new local variable with this name */ if (array_token) { c_token = array_token; local_array_command(lf_head->depth); because lf_head is NULL in that case.
FWIW: my Windows binary compiled with clang 22.1.7 does not exhibit this problem.
