OK, recompiling with those fixes (after configuring using "CFLAGS="-O0
-g3" ):
1rst step: ./configure
2nd step: fix src/config.h as indicated
3rd step make

You're right, sorry.

It's the same
Note that the immediate crash occurs only when MALLOC* variables are
defined.

I understand, I've also disabled graphic libraries execpt png (using a
emacs dedicated version)
I'm on aix 6.1, since I've been unable to compile on AIX 7.1:
configure: error: Emacs does not support `powerpc-ibm-aix7.1.0.0' systems.
If you think it should, please send a report to bug-gnu-emacs@gnu.org.
Check `etc/MACHINES' for recognized configuration names.
Used gcc binary from 6.1 there ^^^
Since I'missing native 7.1 compatible compiler to re-boostrap gcc.
NB: I won't be reachable at my office tomorrow, will return only friday
Next week, won't be very available until Thursday too.
