[PD] Runtime error

[ggkarman at musicologia.com]

Dear list,

Lately im getting this error after running one of my patches after a few
minutes, even with no interaction:
the following msg pops up

------------------------------------
Microsoft Visual C++ Runtime Library
------------------------------------
Runtime Error!!

Program h:\pd\bin\pd.exe

This application has requested the Runtime to terminate it in an unusual
way. Please contact the application's support team for more information.

         ----
         |OK|
         ----
----------------------------------------

of course Pd (0.38.3) stops doing audio and crashes.

I havent seen this kind of error before... ¿any suggestions?
