https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D206551 --- Comment #3 from CTurt <ecturt@gmail.com> --- In the disassembly of `libiconv.so`, the check is performed on an `unsigned int` for some reason: unsigned int v24; ... && v24 <=3D 0x41000 I'm not sure why this is, considering the type of `ia_data` is `int`, which should imply `signed` by default. However, this means that it's not actually triggerable; `EINVAL` is returned for an `ia_data` of `-1`. I've tested on FreeBSD 9.0, and 10.2 --=20 You are receiving this mail because: You are the assignee for the bug.=
