A CU faced with a crash.
Lastly, it turned out that the crash is the same to 6195047,
which is caused that vm wrote data beyond boundary of array.

The CU could resolved the crash itself by the fix for 6195047,
but they also found another possible bug that vm runs
with un-initialized local variable during their investigation.

They sent their report, 1st half is related to analysis of crash(6195047)
and 2nd half is related to possible bug().
Please search the word, "POSSIBLE BUG" in their report.
They think some local variable must be initialized.

The report is too long to write their report fully in this description section.
I have attached their report, New-report-about-possible-bug.txt.
