From: Jörg Krause Date: Thu, 9 May 2019 11:04:38 +0000 (+0200) Subject: package/libupnp18: add upstream patch to fix runtime crash with musl X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=165fcefc60f6f4054f01702ae74546f019fbbf9b;p=buildroot.git package/libupnp18: add upstream patch to fix runtime crash with musl Applications build with a musl 1.1.20+ toolchain and linked with libupnpp will crash at runtime with `Illegal instruction` as musl is more strict with trying to detach an already detached thread resulting in undefined behaviour.
