I bisected it again w/ a fixed test script, got the same bad commit script and double checked, that this commit is really the culprit which crashes a user mode linux kernel at my 32bix x86 stable Gentoo running 2.6.35.6 vanilla kernel as host system and 2/ gcc version 4.4.3 (Gentoo 4.4.3-r2 p1.2) and glibc-2.11.2-r1 in the tool chain.
The crash info is ... * Starting local ...
