Examining the User-Reported Issues With Upgrading From GCC 4.7 To 4.8 148

Nerval's Lobster writes "Developer and editor Jeff Cogswell writes: 'When I set out to review how different compilers generate possibly different assembly code (specifically for vectorized and multicore code), I noticed a possible anomaly when comparing two recent versions of the g++ compiler, 4.7 and 4.8. When I mentioned my concerns, at least one user commented that he also had a codebase that ran fine after compiling with 4.6 and 4.7, but not with 4.8.' So he decided to explore the difference and see if there was a problem between 4.7 and 4.8.1, and found a number of issues, most related to optimization. Does this mean 4.8 is flawed, or that you shouldn't use it? 'Not at all,' he concluded. 'You can certainly use 4.8,' provided you keep in mind the occasional bug in the system."
