Details:
I don't know whether this bug is triggered on all cross-compilation scenarios
(or indeed on native-compilation scenarios), because I haven't tried many.
However, when doing a armv7l-unknown-linux-gnueabihf to
x86_64-unknown-linux-gnu build using glibc 2.27, gcc 7.3.0, binutils 2.30, I
get a compilation error when linking libglob.a:
glob/libglob.a(glob.o): In function `glob':
glob.c:(.text+0x53a): undefined reference to `__alloca'
glob.c:(.text+0x75b): undefined reference to `__alloca'
glob.c:(.text+0x7fc): undefined reference to `__alloca'
glob.c:(.text+0x8de): undefined reference to `__alloca'
glob/libglob.a(glob.o): In function `glob_in_dir':
glob.c:(.text+0x1756): undefined reference to `__alloca'
glob/libglob.a(glob.o):glob.c:(.text+0x1831): more undefined references to
`__alloca' follow
collect2: error: ld returned 1 exit status
Makefile:655: recipe for target 'make' failed
make[2]: *** [make] Error 1
make[2]: Leaving directory '/media/random/ws/WS/build/make-4.2.1'
Makefile:798: recipe for target 'all-recursive' failed
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory '/media/random/ws/WS/build/make-4.2.1'
Makefile:534: recipe for target 'all' failed
make: *** [all] Error 2
This appears to be caused by a change in the preprocessor symbols that are
defined when using glibc 2.27. I'm able to work around it trivially by using
the attached patch, but I don't know if this is a good approach to correct the
issue.
