Summary0001557: Compile error: "void function cannot return value", in xdebug_stack.c, line 1159

Our PHP was compiled using the Solaris Studio 12.6 compiler instead of GCC.

The "make" fails on xdebug_stack.c, with the error:
"{path}/xdebug_stasck.c", line 1159: void function cannot return value"

Steps To Reproduce

export CC=cc
export CFLAGS="-m64"

phpize --clean

./configure --enable-xdebug

Additional Information

The function xdebug_build_fname() is declared as a void function. Yet, within the function, there is a recursive call to itself, on line 1159.

I suspect that the GCC compiler doesn't complain about this, or only generates a warning. But the Solaris Studio compiler errors out altogether.

Removing the "return" from this line causes the code to compile. I suspect that is the fix.

TagsNo tags attached.

Fixed in GIT - thanks for your report!

It's curious why GCC doesn't warn about this though. I did have a try at finding out what the C standard actually says, but couldn't find it either way in there either. Let's hope this fixes the compile for you.
