[Mickael Viey]

Package: csound

Version: 1:6.08.0~dfsg-1
Severity: normal

Dear Maintainer,


the m instruction doesn't work as expected this score make a segfault 
when run:

<CsoundSynthesizer>
   <CsOptions>
   -odac
   </CsOptions>
   <CsInstruments>r
sr     =        44100
;kr     =        4410
ksmps  =        256
  0dbfs = 40

     instr 1
                     ;xamp,     ;kcps    xcar         xmod kndx        
ifn     iphs
         a1 foscil  p4,         p5,     1,           p7, p6,         
1,     0
      out a1
     endin


   </CsInstruments>

     </CsScore>
</CsoundSynthesizer>


here the output when run this with csound:

the debian version of this package seems to be buggy. I will make 
another report about another bug soon.


I join the csd file wich cause the segfault for test purpose.


Thx
