[uml-devel] backtrace of uml crash on mysql-server start

["Sebastian Böhm" <seb@exse.net>]

Hi,

finally I was able to produce this stracktrace with 2.4.26-um1 (host 
also 2.4.26)
It happend during a mysql-server start. (I can reproduce this quite 
constant, if you have further questions ...)

maybe something with ipc ?
