Created attachment 346951 [details] g++ reproducer source code Description of problem: g++43 compilation error with customer application using the BOOST libraries. Not reproducible on x86_64 and not reproducible with gcc44-preview. This is *only* reproducible with gcc43 on i386. Please ensure this is no longer an issue for the gcc44 release candidate in RHEL5.4. Version-Release number of selected component (if applicable): # g++43 -v Using built-in specs.

This request was evaluated by Red Hat Product Management for inclusion, but this component is not scheduled to be updated in the current Red Hat Enterprise Linux release. If you would like this request to be reviewed for the next minor release, ask your support representative to set the next rhel-x.y flag to "?".
targeting gcc43 in rhel5.5. gcc and gcc44 in 5.4 are not affected.
That doesn't make any sense, because gcc44 replaced gcc43 in RHEL5.4, so we won't ever ship gcc43 again.
ah, I thought gcc43 was going to continue to be shipped (along with gcc44), but if gcc44 obsoletes 43 then there will be no issue since the problem only occurs with gcc43. Thanks -- Mark
