[jira] Moved: (MAPREDUCE-1166) SerialUtils.cc: dynamic allocation
of arrays based on runtime variable is not portable
[ https://issues.apache.org/jira/browse/MAPREDUCE-1166?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Allen Wittenauer moved HADOOP-6263 to MAPREDUCE-1166:
-----------------------------------------------------
Key: MAPREDUCE-1166 (was: HADOOP-6263)
Project: Hadoop Map/Reduce (was: Hadoop Common)
> SerialUtils.cc: dynamic allocation of arrays based on runtime variable is not portable
> --------------------------------------------------------------------------------------
>
> Key: MAPREDUCE-1166
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-1166
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Reporter: Allen Wittenauer
>
> In SerialUtils.cc, the following code appears:
> int len;
> if (b < -120) {
> negative = true;
> len = -120 - b;
> } else {
> negative = false;
> len = -112 - b;
> }
> uint8_t barr[len];
> as far as I'm aware, this is not legal in ANSI C and will be rejected by ANSI compliant compilers. Instead, this should be malloc()'d based upon the size of len and free()'d later.
