Hello,

can you test - is it a bug or my build -

calling an instrument with tvar init many times crashes csound:



-odac



sr = 44100
ksmps = 32
nchnls = 1
0dbfs = 1

instr 1
	prints "START"
	t1 init 10
endin




i 1 0 0.1
i 1 0.5 0.1
i 1 1 0.1




(Csound 5.19 from git, opensuse 12.1)

Output:
----------------------

Works for me no crash or anything

PortAudio: selected output device 'default'
writing 256 sample blks of 64-bit floats to dac
SECTION 1:
new alloc for instr 1:
STARTB  0.000 ..  0.500 T  0.500 TT  0.500 M:  0.00000
STARTinactive allocs returned to freespace
end of score.              overall amps:  0.00000
           overall samples out of range:        0
0 errors in performance
Elapsed time at end of performance: real: 0.773s, CPU: 0.050s
87 256 sample blks of 64-bit floats written to dac

Last START stuck as no newline to flush it?  Or is it the early stop that
is the problem

I am using doubles on OpenSuSE12.2 x86_64

....but running under valgrind I see a memory problem
"Source and destination overlap in memcpy"
Will check
