bug with __builtin_apply on gcc > 2.7.2.3

[Mike Heffner <spock at techfour dot net>]

Hi,

I'm using a program that uses nested __builtin_apply calls (a function called
with __builtin_apply calls another function with __builtin_apply). the program
builds and runs fine with gcc 2.7.2.3, but when i use gcc 2.8.1, it will
compile fine, but will SIGFPE(floating point exception)  during runtime when it
returns from
the second function called with __builtin_apply(). i've tried to look at the
gcc code, but couldn't find anything relevant to the problem. 

does anyone know how to fix this? has anyone else experienced this bug and know
a workaround(other than not using __builtin_apply)?

attached is a short program that demonstrates the problem.

thanks,
