[Bug middle-end/36008] Function produces wrong results when inlined.

I have managed to create a test case:

Correct case:

[EMAIL PROTECTED]:~$ gcc-4.3 bravais.c mathfunc.c -O3 -fno-inline
bravais.c: In function ‘main’:
bravais.c:83: warning: incompatible implicit declaration of built-in function
‘printf’
[EMAIL PROTECTED]:~$ ./a.out 
0 

Wrong case:

[EMAIL PROTECTED]:~$ gcc-4.3 bravais.c mathfunc.c -O3
bravais.c: In function ‘main’:
bravais.c:83: warning: incompatible implicit declaration of built-in function
‘printf’
[EMAIL PROTECTED]:~$ ./a.out 
-1 

Sorry for using two files, but the problem disappears if all functions are in a
single file.
