Invalid code generation
Hi,
The code below should print :
a5 is 0
However it prints in my case:
a5 is 4196880
This is failing on Solaris 10 x86-64 with the following C command line:
cc -xarch=generic64 main.c
I think I have the latest patched version of cc:
cc: Sun C 5.8 Patch 121016-01 2006/01/26
Is this a known issue? Is there a workaround?
Thanks,
Manu
