• Linux 4.5.3-1-ARCH deps: update openssl to 1.0.1j #1 SMP PREEMPT Sat May 7 20:43:57 CEST 2016 x86_64 GNU/Linux:
  :

after update gcc version from 5.3 to 6.1.1, the compile of node 0.12.7 failed with segment fault, this issue not happened when compile debug version and i compile 0.12.14 the issue still exist and it disappeared after remove -O3 from makefile.
debug the issue found the reason is:
#0 v8::internal::PagedSpace::Contains (addr=0x0, this=0xd61ff0) at ../deps/v8/src/heap/spaces-inl.h:152 152 return p->owner() == this;
the input argument addr is null, after add a check for the input argument, this issue disappear.

Try building with make CXX="g++ -fno-delete-null-pointer-checks". v0.12 is in maintenance mode and close to being EOL'd so I don't think we'll fix this.

Perhaps if we do another v0.12 release (big if), we could add -fno-delete-null-pointer-checks to the default build flags.

I filed #6737 and #6738 for v0.12 and v0.10 respectively.

Closing this given that support for v0.12 is coming to a close in two days and there will not be any further updates to the v0.12 branch.
