Hi Ben,

Just gave it a go and didn't get so far. I had to modify the CSD to
even get Csound to compile (I'm assumed it's reduced from something
else you were working on) and beyond that, just got a seg fault too.
Running in gdb, I get:

Program received signal SIGSEGV, Segmentation fault.
0x7c918fea in libsndfile_1_dll_iname ()
(gdb) bt
#0  0x7c918fea in libsndfile_1_dll_iname ()
#1  0x7c36b417 in libsndfile_1_dll_iname ()
#2  0x7c90104b in libsndfile_1_dll_iname ()
#3  0x1e0a73ce in libsndfile_1_dll_iname ()
#4  0xe87c3822 in ?? ()
#5  0x00b5d220 in ?? ()
(gdb) Cannot access memory at address 0xb5d220

I'm not sure what's going on here though, and since I'm not compiled
with debug on, can't be more helpful than that.

Anyone else with ideas?

steven
