>Organization:
Queen's University of Belfast
>Environment:
System: SunOS scooby 5.9 Generic_112233-04 sun4u sparc SUNW,Sun-Blade-100
Architecture: sun4
host: sparc-sun-solaris2.9
build: sparc-sun-solaris2.9
target: sparc-sun-solaris2.9
configured with: /scratch/temp/ss/gcc-20030310/configure --prefix=/opt/local/gcc330
>Description:
The compiler generates an internal compiler error when optimizing
for an ultrasparc in fast-math mode. This program compiles OK with
gcc 3.2.2 using the same command line options
>How-To-Repeat:
scooby> gcc -v -c -O1 -mcpu=ultrasparc -ffast-math phymir.c

void p()
{
long int i,j;
float a,b,c,x[1];
x[i] = (a/(((b)>(c)) ? (b) : (c)) - (((i) == (j)) ? 1.f : 0.f));

>Fix:
Omitting any one of the command line options works around the problem.
