This should be a P1 because it involves regressions from gcc 4.4.1 on a primary
target (i686-apple-darwin10 at -m64).

Hi,
I'm seeing some valgrind warnings about illegal reads from addresses if I use
VTA. While compiling newlib I intermittently get segfaults in the compiler for
the attached testcase , but it seems to go away when I run this through a
debugger.
This is with revision r151500.

Example code that triggers the bug on a variety of machines all running gcc
4.1.2 and higher.
#include
inline double sqr(double x){
return x*x;
}
int main(){
double r;
for(r=0.0;r<2.0;r+=1.0){
printf("%e \n", sqr(sqr(sqr(sqr(sqr(r));
}
return 0;
}

I don't trying to rebuild all with 4-byte incoming stack alignment while, but
think to unify this step with full ABI change. For me it may solve migration to
-mregparm=3 ("ix86_regparm = REGPARM_MAX;" for x86_32) and others in

I tried to reproduce this manually (on thallium:/abuild/mjambor/) but
couldn't. I just get the same execution times with or without that
patch reverted... I am not sure what this means or how to proceed from
here.

Is the problem described at http://gcc.gnu.org/ml/fortran/2009-09/msg00046.html
the same or a different one?
There, it is claimed to be a 4.5 regression.
