Malloc failed for 64bit application.

Question

Dear All,
my program has core dump when call malloc function in 64bit multithread programming.
The information from GDB are follow:-
Loaded symbols for /usr/platform/SUNW,Sun-Fire-280R/lib/sparcv9/libc_psr.so.1
Reading symbols from /usr/lib/64/nss_files.so.1...done.

1777 wsd2=(int *)malloc(sizeof(int));
Note: My program already include <stdlib.h>
Anyone knows reasons why malloc() failed in my program. Thx.

You have have a look at the following document on SunSolve (http://sunsolve.sun.com):
