Package: fakeroot
Version: 1.18.4-2
Hi fakeroot developers,
If @LDPRELOADVAR@ is already set, scripts/fakeroot.in separates LIBS with
a space. This works fine for LD_PRELOAD on GNU/Linux, but not for
DYLD_INSERT_LIBRARIES on Mac OS X, which must be colon-separated. So if
you already have a library in DYLD_INSERT_LIBRARIES, this breaks usage of
fakeroot:
dyld: could not load inserted library:
/Users/gthomas/src/debian/b/lib/libfakeroot.dylib /tmp/d.dylib
/Users/gthomas/src/debian/b/bin/fakeroot: line 181: 75294 Trace/BPT trap:
5 FAKEROOTKEY=$FAKEROOTKEY DYLD_INSERT_LIBRARIES="$LIB" "$@"
Fortunately, glibc permits separating LD_PRELOAD with either a space or a
colon (see the comment near line 1658 or so in elf/rtld.c, and the
changelog entry of 1998-02-01). So I propose that you make
scripts/fakeroot.in line 168 use a colon, which will fix the bug on OS X
and continue to work fine on GNU platforms. (Because glibc tokenizes at
_both_ spaces and colons, there is no problem if the existing LD_PRELOAD
variable includes multiple preloads separated by spaces.)
I don't know if fakeroot supports any platforms that require
@LDPRELOADVAR@ to be space-separated and not colon-separated, which would
make my suggested fix not work.
