Can we repeated this issue, or it is random?  I have try it use my
current gcc version, it has no issue.

If it can be repeated in the latest version, I shall use version compine
(and try step by step) to fix it.

If real random issue, if possible, please help repeated and generate
coredump file, and put it to a place to let me get back for analysing.


Thanks.
