Issue ID: 13229
Summary: RangeError in inlined function prints wrong module
name (but right line)
Product: D
Version: D2
Hardware: All
OS: All
Status: NEW
Severity: normal
Priority: P1
Component: DMD
Assignee: [email protected]
Reporter: [email protected]
When a range violation occurs in an inlined function, the error message
mentions the module which calls that function, not the module where it is
defined. However, the line number corresponds to the file where the function
is defined.
As this points to a wrong line of the source, the error can be very confusing
the first time you encounter it. It surely looks like "debug capabilities
broken".
-----caller.d-----
module caller;
import other;
// lines 3-5 contain no code
void main () {
fun (2);
}
-----
-----other.d-----
module other;
int [2] x;
void fun (int i) {
x[i]++;
}
-----
When we run "dmd caller.d other.d", we get the correct message:
[email protected](4): Range violation
However, add -inline, as in "dmd -inline caller.d other.d", and we see the
error:
[email protected](4): Range violation
As you can see, line 4 of caller.d contains only a comment and so can not
generate any errors.
This is reproducible for me on DMD 2.065.0 and DMD 2.066.0-b6 on Win32 and
Win64.
