<div dir="ltr">Hello,<div style>I have a problem with ltrace (pulled from git and built today). Every binary which i try to ltrace ends up with SIGSEGV in the same place - <font face="courier new, monospace">SYS_ioctl(1,,,)</font> (example attached below). I'll be grateful for any hints on what can cause such behavior...</div>
