From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4) Gecko/20030701 Description of problem: Executing a piece of custom-compiled code, build on a redhat 7.3 box with gcc-c++-2.96-113 and libstdc++-2.96-113 does not properly function using compat-libstdc++-7.3-2.96.118 on RH9. Replacing /usr/lib/libstdc++-3-libc6.2-2-2.10.0.so with the one from the redhat 7.3 distribution results in proper operation of the code in question - so the issue is most definately this library, included in compat-libstdc++-7.3-2.96.118. Version-Release number of selected component (if applicable): compat-libstdc++-7.3-2.96.118 How reproducible: Always Currently working on creating a minimized testcase to exhibit the bug, but as it is closed-source code this is a nontrivial task. Are there *known* incompatibilities between the "real" RH7.3 libstdc++ and the one included in compat-libstdc++ on RH9?
There were some issues with -2.96.118, see e.g. #97372, but without a testcase hard to say.
