Again: it's really good idea to test vanilla nginx, without any 
patches and 3rd party modules, especially when debugging such 
subtle problems.  Even trivial patch might cause unspecified 
behaviour e.g. if it applied incorrectly due to context code 
changes.  And the similar thing applies to 3rd party modules.

I need a gcc command as shown during "make", like this:

gcc -c -pipe  -O -W -Wall -Wpointer-arith -Wno-unused-parameter -Wunused-function -Wunused-variable -Wunused-value -Werror -g  -I src/core -I src/event -I src/event/modules -I src/os/unix -I objs \
		-o objs/src/core/nginx.o \
		src/core/nginx.c
