Hi,
similar error was reported for HP, too.  I will look into it now.  I hoped it
is same as the Toon's problem (that hack I removed caused quite bad propagation
across unitialized datastructured)

Yesterday I analyzed last problem I reproduced Mozilla and those are due to the
fact that we don't do type compatibility checking when doing indirect inlining
and in LTO type merging. So different than this one.

Duh, will fix that!
