Subject: [PATCH 2/4] Fix an possible overflow error
|
||
|
|
|
||
|
|
Got:
|
||
|
|
"specified bound 2048 exceeds the size 19 of the destination"
|
||
|
|
when -O2 is used, and a "*** buffer overflow detected ***" error output
|
||
|
|
with no backtrace.
|
||
|
|
|
||
|
|
With -O0, it's gone, guess it's some gcc optimization problem, and the
|
||
|
|
size there is wrong anyway, this patch could fix it.
