- Subject: [rfc] Clarify shared library warning
This function, added recently by Alex, just saved me hours. I was looking
back at an old bug report, and some inexplicable symbols that seemed to
start in the middle of functions. And right there was a message from GDB,
not present last time I looked at the testcase:
warning: .dynamic section for "/lib/libc.so.6" is not at the expected
address
The tarball that went with the core dump had the wrong libraries in it.
No wonder it didn't work.
But this warning isn't very self-explanatory. I was thinking something
like the below, in addition. How does this sound?
warning: .dynamic section for "/lib/libc.so.6" is not at the expected
address
warning: the wrong version of the shared library may have been found
