             Bug #: 52131
           Summary: dynamic allocation?
    Classification: Unclassified
           Product: gcc
           Version: 4.1.2
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: paulmc@walla.co.il


Hi,

It’s seems that the next lines don’t arise any error or warnings - 

int bufSize = strlen(username) + 1 + strlen(column) + 1 ;
char buf[bufSize];

As far as I know, a buffer cannot be declared with size that known only on
runtime.

This is a documented extension, see
http://gcc.gnu.org/onlinedocs/gcc-4.6.2/gcc/Variable-Length.html#Variable-Length

Use -pedantic to get a diagnostic.
