testcase select03 encountered segmentation fault

[YeechouTang]

Hi,

We encountered a segmentation fault while executing the select03 test case.

./runltp -f syscalls -s select03 ...

Summary:

It seems that the test case ran successfully. However, I found a crash file in the /var/crash directory.

Below is the output from the bt command in gdb.

Core was generated by `select03'.
Program terminated with signal SIGSEGV, Segmentation fault.
