TTBOMK, "dtrace" is a Solaris tool, and I haven't heard about it being
available on CentOS.
I assume this is a typo, and Johan meant "strace". I agree this might
provide some helpful info.

Before researching that any further:
Do you have any specific reason to work as root?
If not (or if your only reason is laziness), please do your operations
as non-root, "normal" user: It is safer for you, and it may alter
Also, is "/usr" your current directory?
In that case, I propose you "cd" to some other place where it may make
more sense to do your work and to keep your files.

I am used to SIGSEGV causing a core dump, and in this case a stack
backtrace would definitely be interesting.
You may need to install a debugger for this, preferably "gdb".

So if this issue persists for non-root in (or below) a home directory,
and you get a core dump there, a call
gdb /PATH/TO/mysql 2>&1 | tee TRACE
(capital words replaced as appropriate) will start the debugger, typing
will create the backtrace, and
will get you out again.
Then, post again here, and paste the contents of file "TRACE".
Also, don't forget to include your "configure" (or rather: "cmake") line
and the exact versions of CentOS and gcc.
