Maybe this is some trace:

"checking whether to force non-PIC code in shared modules... yes"

x32 configure says "no" here.

Looks like wrong conditions in hand-written asm code.

Also I can see many warnings like:
Zend/zend_types.h:134:3: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
- to be verified if proper types are used during int/ptr arithmetic...
