You need to turn on line reporting, as my examples posted earlier showed.
See below.

Please post a simple example; I do not get this behaviour.

Here is what I get when I turn on both flags that control syntax error
reporting:

(%i2) report_synerr_info : report_synerr_line : true$

(%i3) load("/tmp/err.mac");

/tmp/err2.mac:line 2:incorrect syntax: Y is not an infix operator
\nx:1 y;
      ^
Here are the contents of the two files:

err.mac:

x:2* y;
load("/tmp/err2.mac");

err2.mac:

w : sin(1);
x:1 y;
