Idea about @subject started with ongoing customer support case that originated https://bugzilla.redhat.com/show_bug.cgi?id=1778236 [Problems linking to zlib corrected if zlib is linked with -Bsymbolic-functions] when doing some research, it appears Ubuntu has it by default for some time. This is currently only a suggestion and/or request for comments. Some extra detail in https://bugzilla.redhat.com/show_bug.cgi?id=1778234 [Request For Comments: -Bsymbolic-functions in LDFLAGS by default] Basically, there would be a few issues, most times in broken code, and the valid cases could be worked around removing -Bsymbolic-functions. The biggest advantages are far less relocations, for example, that should mean faster load time, and avoids several issues with symbols being clobbered by symbols from another library.
If I understand correctly then it will also mean that LD_PRELOAD will not work for any call made from the library to itself, but would still work for calls made from other libraries.
