seems that problem is with this commit:

1.5.2.1 +7 -2 src/gnu/usr.bin/cc/cc_tools/freebsd-native.h
I had very similar problems with ACE wrappers (segfaults on return from
function)/
First, I thought that problem might be introduced by libc_r fixes.
There were also a couple of binutils/gcc updates in -stable so
I downgraded my sources to 4.2-RELEASE and also checked out libc_r before
Dan Eischen fixes -- no luck. After that I checked out
src/Makefile.inc1 1.141.2.15 and freebsd-native.h 1.5. Now I have all ACE
wrappers tests (that should work) running perfectly.
This commit also introduces binary incompatibility -- C++ code
compiled on 4.2-RELEASE cannot be run on RELENG_4 built before this
commit.
Please try to backout this change in your local source tree, rebuild
world, relink your programs and libraries -- I think mysql problems will
went away also.
Now I am rebuilding world with Dan Eischen libc_r fixes to see if they
would not break anything (they should not -- Dan confirmed that he tested
his fixes with ACE wrappers tests on -current)
