Subject[Cs-dev] crashes with SIGFPE (widgets, graphs, portaudio?)
I have been experiencing some crashes on Windows with a combination
of flags. I believe this is related to Oeyvind's crash report from last week.

If I run the fl.csd example (from /examples)

csound -odac -d fl.csd

all is well. But if I add -iadc

csound -odac -iadc -d fl.csd

I get a floating-point exception (SIGFPE) and a crash.

Now if I take -d out

csound -odac -iadc fl.csd

all's well again.

That does not happen with the MME module (-+rtaudio=MME), so I
suspect it's portaudio-related. But why the interaction between
graphics/no-graphics? Any suggestions? Has anyone touched
these bits of code? It does not seem to happen if I am not
using the widget opcodes.
