[Bug gprof/11524] New: segmentation fault when use --external-symbol-table option

[hongsheng611 at gmail dot com]

the bug is in the file: binutils-2.20/gprof/corefile.c 

in the function:  static int num_of_syms_in (FILE * f)

line 520:   while (!feof (f) && fgets (buf, sizeof (buf), f))

this is wrong! because the type of buf is char *, so sizeof(buf)=4 

this would cause segmentation fault when use --external-symbol-table option.

it should be changed to :   while (!feof (f) && fgets (buf, BUFSIZE - 1, f))
