Buffer overflow detected when used with sjiswrap.exe and compiled with fortify hardening

Fortify hardening seems to be causing errors after melee added sjiswrap.exe to the build. I can simply disable the fortify hardening when building wibo, but is this something I should be concerned about?

Aborted

Reproduce the reported failure using the sjiswrap.exe and wibo command with fortify hardening enabled. Determine whether the abort originates in wibo, sjiswrap.exe, or the hardening configuration, then document a confirmed fix or reproducible limitation.
