Using B19 release of gdb and gcc, I recently created a program to test a
function that removed trailing blanks from a string, in place. That is, it
moved \0 to the first of one or more trailing blanks. This would change
"123 " to "123" or "a b c " to "a b c", for example. To test this, I
created a main, created some strings and called the function. This
combination I tested using gdb, and everything appeared to work as I
expected. However, when I ran the program directly from DOS, it aborted
with STATUS_ACCESS_VIOLATION. I eventually realized that the problem was
caused by me passing a pointer to a literal ( char *test1 = "123 "; ),
rather than a pointer to a character array. When I fixed this ( char
test1[] = "123 "; ), the program ran as expected.
My question is, why did this run without an error under gdb, when it
aborted when run under DOS?
