rtorrent crashing on musl+llvm system #1221

Open alfredfo opened 1 year ago

Hi, rtorrent is crashing on my ThinkPad server running Gentoo with musl libc and clang-15 as system compiler

Starting program: /usr/bin/rtorrent 

Program received signal SIGSEGV, Segmentation fault.

A possible work around would be to compile libtorrent and rtorrent with GCC. It looks like this crash is related to the clang implementation of the c++ standard library. You can configure a GCC Fallback Environment on Gentoo Linux. https://wiki.gentoo.org/wiki/Clang#GCC_fallback_environment
