Summary: Missing warning "makes pointer from integer without a

Product: gcc

Stripped down failing c source.
Hello,
when compiling the attached source, i do not get the "makes pointer from
integer without a cast" warning.
I see this behavior with
- gcc (GCC) 4.9.2 20150212 (Red Hat 4.9.2-6)" on fedora 21.
- gcc (GCC) 4.9.0
but NOT with
- gcc (GCC) 4.7.2
- gcc (SUSE Linux) 4.5.1 20101208
To miss the warning, compile with:
gcc -Wall -W --save-temps -c missing_warning.c -o missing_warning.o
Without the "--save-temps" option, the warning appears.
Without the newline in the assert(1) the warning also appears!
Maybe this is related to or a duplicate of
