<p>Hi,</p>
<p><br>
</p>
<p>After another test, It seems that the m statement which cause the
segfault.</p>
<p>Consider the two attached csd files. One contains a "m" statement
and make a segfault, the other doesn't contain it and work as
expected.</p>
<p>a link toward documentation about this, I think I use it
correctly (the file worked on my previous csound version on Debian
Jessy):<br>

Package: csound<br>

Version: 1:6.08.0~dfsg-1<br>
Severity: normal<br>
<br>
Dear Maintainer,<br>
<br>
<br>
I have some csd files I made on another platforms
which generate<br>
segfault when running with this version of csound.
After diagnostic It<br>
appears that the macro system which is
responsible.<br>
<br>
By example, this macro works:<br>
#define TIME # 0.25 #<br>
#define freq # 146 #<br>
<br>
<br>
#define T # $freq #<br>
#define Am # $freq * 17 / 16 #<br>
#define AM # $freq * 9/8 #<br>
<br>
But If I had this after te last line:<br>
<br>
#define E # $freq #<br>
<br>
I get a segfault. I will join the complete csd
file I used for my tests.<br>

Weird. I can reproduce on a stretch docker
container, but I can't<br>
reproduce on sid, either with 6.09 or rebuilding
6.08 . I ran out of<br>
time, but could you try rebuilding csound and see if
the problem<br>
persists?<br>
<br>

Hi,<br>
<br>
I am not sure what you mean by "rebuild" but this is
what I done:<br>

<div>Thanks, but I meant recompile the csound sources, not
just reinstall.</div>
<div><br>
</div>
<div>Anyway, I have debugged some more. Turns out the
error in sid is still present, it just doesn't cause a
crash. I have forwarded upstream to the above url. </div>
<div><br>
</div>
<div>The error is not due to the macro, but due to the 3/2
p7. This is invalid syntax, and that triggers the
crash/malfunction (the crash is in the error printing
code, heh). You can work around the problem by fixing
the syntax error and passing 1.5.</div>
