[g-a-devel]GNOME Speech Weirdness

[Marc Mulcahy <marc mulcahy sun com>]

Hi All,

It seems this weirdness, or an incantation of it, is reproduceable with the 
new festival driver as well.  I've attached a stack trace of a crash on my 
machine, reproduceable with the following steps:

1. Run the test-speech program
2. Select the Festival driver (number 2 on my system)
3. Select the parameter test (number 1)
4. Pick the "rate" parameter (number 1)
5. Set it to any value.
6. Choose zero to exit the test.
7. Choose 1 from the tests menu again

Blam!

It looks to me as though something has caused the stack to blow up (entry 
to g_malloc shows n_bytes to be corrupted)a but the value passed to 
g_malloc from CORBA_string_alloc looks OK.  It appears to be attempting to 
throw a "COM failure" exception, but this is the same behavior I was seeing 
with the Viavoice driver when it was simply trying to demarshal a string 
within a sequence of structs.

Hmmm...

I have a bad feeling that this is something dumb I'm doing and not 
seeing...  Flames welcome <sigh> :)
