[Dev-C++] Help me.... strange char functions on MinGW

[Rafael O. L. <raf...@gm...>]

Hi All.

I'm learning C with Dev-C++ and MinGW and a wrote such function like this:

#include <stdio.h>

char *strset(char *s, char ch);

main()
{
printf("%s", strset("TEST, TEST", 'c') );
getchar();
}

char *strset(char *s, char ch)
{
int i;

for(i = 0; s[i]; i++)
s[i] = ch;

return s;
}

that would have to fill the string argument with the char ('c') and print
it.

string: "TEST, TEST"
result: "**************"

But, I have a Access Violation, and program crashes.

I've tried to compile in LCCWin32 and runs fine.
Then, I've tried, again, to compile in mingw and ran on MSYS, suprise....
works fine too.

But in a DOS shell, the same mingw compiled program gives me a Access
Violation... Why!!!!????

Please Help...
