            Bug ID: 67759
           Summary: Missing warning "makes pointer from integer without a
                    cast" after multiline assert
           Product: gcc
           Version: 4.9.2
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3

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
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=60100
and/or
