Bug 733 – std.conv.toFloat does not catch errors

In rare cases, toFloat will not throw an exception on invalid input. Also affects toDouble and toReal. ------- import std.conv; import std.stdio; void main() { char[] b = "\x00"; bool ok = false; try { float f = toFloat(b); } catch (ConvError e) { ok = true; } assert(ok); } ------- General fix: f = strtof(sz, &endptr); if (getErrno() == ERANGE) goto Lerr; - if (endptr && (endptr == s.ptr || *endptr != 0)) + if (endptr && (endptr == sz || *endptr != 0)) goto Lerr; return f;

Fixed dmd 1.023 (already worked in 2.006)
