Hi after discussing it a bit on #glibc on freenode i thought i should
shed some light on an regression ive found with a glibc commit so you
guys know about it, f81ddabffd76ac9dd600b02adbf3e1dac4bb10ec this
commit makes steam games like Cities: skyline, Plague inc: evolved,
Kerbal Space Program and such using mono crash rather immediately with
"2double free or corruption (out)" , i have tried stracing it but it
yielded not much more info then this,
https://gist.github.com/anonymous/4af155e36475a07d3bced72e6d2ff9a1
the strace is shortened down to the very last lines where the error happends.
keep in mind tho that the games provide their own mono runtime that
are more or less very old, and it might already be fixed in upstream
mono. and these games runs fine once i stepdown a commit to
1a49fc59e42513247eaeac3feac6b099157eea7c
with my very basic knowledge all that commit seems todo is change some
glibc internals, and if nothing else i will just simply make a steam
bugzilla/bugtracker report and maybe mono bugtracker report once glibc
releases a version including this commit.
