gdb received signal SIGSEGV before even entering main!

[jing.dong]

The program I ran gdb on a very standard hello world program, it crashes even 
before main is entered. 
Anybody have an idea how to solve this problem?
Any help is appreciated.

The following is a running script:

/home/john> gdb -nw a

(gdb) b main
Breakpoint 1 at 0x4010b6: file hello.c, line 3.
(gdb) r
Starting program: /home/john/a.exe

Program received signal SIGSEGV, Segmentation fault.
0x77e75a3d in _libkernel32_a_iname ()
(gdb) q
The program is running.  Exit anyway? (y or n) y
