Bug #: 15510
Summary: getopt() do NOT REORDER the argv[] when specify the
-std=c99 option
Product: glibc
Version: 2.15
Status: NEW
Severity: critical
Priority: P2
Component: libc
AssignedTo: unassigned@sourceware.org
ReportedBy: 1533963612@qq.com
CC: drepper.fsp@gmail.com
Classification: Unclassified
Created attachment 7035
--> http://sourceware.org/bugzilla/attachment.cgi?id=7035
the source code, complie it with and without -std=c99 to see the difference
using the code show in getopt(3), complie it using gcc c99 option(-std=c99),
then if we input like this:
./a.out name -t 10
the getopt() can not find the -t option and its value. it just stop at name.
but if we complie it without -std=c99, things get right, we will get the -t and
its value, and name is reorder at last position.
