Hi,
the vasnprintf() now intentionally crashes on macOS 10.13 when the formatting string contains %n and is dynamically allocated, for more, see
This problem affects all users of gnulib's vasnprintf implementation which are at least the following (found by find . -name "vasnprintf.c" in sources which I use for compiling Geany - but there may be more):
./pkg-config-0.29.2/glib/glib/gnulib/vasnprintf.c
./bison-3.0.4/lib/vasnprintf.c
./gettext-0.19.8/gettext-tools/libgettextpo/vasnprintf.c
./gettext-0.19.8/gettext-tools/gnulib-lib/vasnprintf.c
./gettext-0.19.8/gettext-runtime/intl/vasnprintf.c
./gettext-0.19.8/gettext-runtime/libasprintf/vasnprintf.c
./glib-2.52.2/glib/gnulib/vasnprintf.c
Without any change I get the first error when compiling bison:
CCLD src/bison
GEN doc/bison.help
/bin/sh: line 1: 77605 Illegal instruction: 4 src/bison --version > doc/bison.help.tmp
make[2]: *** [doc/bison.help] Error 132
make[1]: *** [all-recursive] Error 1
make: *** [all] Error 2
*** Error during phase build of bison: ########## Error running make -j 9 *** [17/24]
All of the above files should probably be patched - all of them already contain a fix for the same issue under Windows which behaves the same way - I just simply tried to add a simple condition "|| defined __APPLE__" to the place where this is tested and the Windows code seems to work fine. See the above gnulib mailing list link for more info.
