[PD-dev] [PD] Problem in os x 10.5.1?

[David Plans Casal]

Hello

I have spent a bit of time with gdb and pd latest cvs, and I can now  
report that the problem with fork() and exec'ing causing  
CoreFoundation errors in mac os x is not, as Miller suspected, in  
t_tkcmd.c (circa line 423), but actually in s_inter.c, beginning line  
1013, where:

#ifdef UNISTD
         childpid = fork();

...is called but execl() is not called until 1103.

I can't quite tell why it's complaining (since we -do- call execl),  
but of course there is a whole lot of sprintf going on between the  
two, so...

Any suggestions, anyone?

David
