Re: strtok, bus error

[Bryan Christ <bryan.christ@gmail.com>]

 char src[]  = "hello world #"; is an automatic variable (char array)
which is both read and write.
char *other = "hello world #"; is a char * (which points to a string)
of text allocated in the program's text (Data/BSS) area which is read
only.
