Yes, the build is always from a pristine source directory (scripted).
I'm sorry to admit that I do not know how to produce a meaningful backtrace. I
have the core file and gdb installed on the machine, yet not in the environment
(solaris zone) where apache runs. Could you give a pointer on how to produce a
helpful backtrace?

can you give me the backtrace? and btw, did you build that from a pure
environ(make clean, make install).

I tried php5.4-201201041430.tar.bz2, and the problem persists (Solaris i86pc):
