>Description:
When compiling simple helloworld program, cc1 from gcc 4.5.4 dumps core.

My helloworld is here.
$ cat test.c
#include <stdio.h>

int main(void)
{
printf("Hello, world\n");
return 0;
}

And error message from gcc -v is here.

COLLECT_GCC_OPTIONS='-v' '-mno-synci'
 /usr/libexec/cc1 -quiet -v test.c -quiet -dumpbase test.c -mno-synci -auxbase 
test -version -o /var/tmp//cc05DK2k.s
signal 1: epc 0x63d53c
gcc: Internal error: Segmentation fault (program cc1 received signal 11)
Please submit a full bug report.
See  for instructions.

gdb from base dumps core too, and I cannot investigate this problem deeper.
        
>How-To-Repeat:
gcc -v test.c
        
>Fix:
        
I have no idea, please fix it.
