>Organization:
>Environment:
SunOS dev00011 5.5.1 Generic_103640-32 sun4u sparc SUNW,Ultra-4
Reading specs from /usr/local/lib/gcc-lib/sparc-sun-solaris2.5.1/3.0.1/specs
Configured with: ../gcc-3.0.1/configure  : (reconfigured) ../gcc-3.0.1/configure 
Thread model: posix
gcc version 3.0.1

>Description:
Repeat of Problem 4611 with the source trimmed to the absolute minimum in order for the problem to appear.
Also, 6 different ways to make the problem appear and disappear. (hope this helps more than the 4611)
>How-To-Repeat:
gcc -g -O2 -c -o A.o A.c -save-temps
>Fix:
Any of the following will prevent the problem from appearing.

1. Remove -O2
2. Change the length of facilityCode_CA[49] to anything less than 49
3. Change the initialiser of dumpIfGreaterThan_D from INT_MAX to zero
4. Remove the line dumpIfGreaterThan_D = 0.0 from the switch statement
5. Remove the printf containing the dumpIfGreaterThan_D variable
6. Change the value of MAX_STATS to anything LESS than 84
