please check upstream tickets and link the matching one here if one exists or create a new one. https://github.com/rofl0r/proxychains-ng/issues
I made an attempt to reproduce with current proxychains-4.14 and pending proxychains-4.17 (https://github.com/gentoo/gentoo/pull/35339). Could not reproduce a crash with either; I didn't try with the openwrt build, but with linux-6.6.16 doing a make clean between each iteration. 50 loops at -j32 HOST_JOBS=-j32 PKG_JOBS=-j32 with no segfaults. I do see some notes in the ChangeLog for 4.13 and newer about fixes that might be relevant. Xuefer I see you were asked in the upstream bug to try to reproduce with a newer proxychains. Are you able to reproduce? And if so, can you share more about your build environment please? I see you have splitdebug enabled but maybe gdb could not find the debug symbols, and/or they weren't built for the openwrt packages and it's that bash that's dying?
