Problems with egcs 2.290.27 and 2.91.66

[Peter Alan Burton]

Greetings,

I am getting a segmentation fault when I try to execute a program (on a 
Intel/RedHat 6.0 system) that was recreated on an Intel/RedHat 6.0 system 
from objects built on an Intel/RedHat 5.1 system.

Both systems have no patches applied.

Running the 5.1 executable on the 6.0 system does not cause the problem.

Peter


Program:

#include <stdio.h>
#include <stdarg.h>

void p2c (char * pFormat, ...)
   {
   va_list Arg_Ptr;
   va_start(Arg_Ptr, pFormat);
   vfprintf(stdout, pFormat, Arg_Ptr);
   }

int main(void)
   {
   p2c("%s %s\n", "Hello", "World");
   return 0;
   }
