Linux, current compiler as of June 30. The following code:

import std.string;
void main() {
char* num = "x";
char[] testName = std.string.toString(num);
printf("%s\n", std.string.toStringz("1234567890123" ~ testName));
printf("%s\n", std.string.toStringz("12345678901234" ~ testName));
printf("%s\n", std.string.toStringz("123456789012345" ~ testName));
printf("%s\n", std.string.toStringz("1234567890123456" ~ testName));
printf("%s\n", std.string.toStringz("12345678901234567" ~ testName));
}

will output:
1234567890123x
12345678901234x
123456789012345x
1234567890123456x
12345678901234567x

Notice the accented y? It shouldn't be there. This only occurs if the total
string is 16 characters long, and includes a char[].

I cannot reproduce this bug.

Using: DMD 0.9.4, RHEL 3.0, 2.4.21 kernel, GCC 3.2.3, can't think of
anything else important

Also tried on my WinXP system out of interest but no bug there either ;)

My output on both systems is simply:

1234567890123x
12345678901234x
123456789012345x
1234567890123456x
12345678901234567x

What Linux distro and version are you running, with what kernel, and what
version of GCC?

**** This bug is caused by a terminating uninitialized char **** Report it in the bugs newsgroup, and tell them the above. Meanwhile, I suggest you do what I did - go back to DMD 0.92. Arcane Jill

This problem was corrected in 0.94, check the date on your copy of
