new gcc bug

[Paul dot Zimmermann at loria dot fr (Paul Zimmermann)]

* the exact version of GCC; 
bash-2.04$ gcc -v
Reading specs from /usr/local/lib/gcc-lib/ia64-hp-hpux11.20/3.2/specs
Configured with: ../gcc/configure --enable-languages=c,c++ --host=ia64-hp-hpux11.20 --target=ia64-hp-hpux11.20 --with-ld=/usr/ccs/bin/ld --with-gnu-as --enable-libstdcxx-v3 --disable-checking
Thread model: single
gcc version 3.2 20020329 (experimental)

* the system type; 
bash-2.04$ uname -a
HP-UX spe175 B.11.22 U ia64 0319544412 unlimited-user license

* the options given when GCC was configured/built; 
See above.

* the complete command line that triggers the bug; 
gcc bug.c
Given output:
bash-2.04$ ./a.out
q=4243519447

Expected output:
bash-2.04$ cc bug.c; ./a.out
q=60

* the compiler output (error messages, warnings, etc.); and 
No output.

* the preprocessed file (*.i*) that triggers the bug, ...
