<tim> hrm, it seems related to glibc having been compiled with
_FORTIFY_SOURCE=2 or something
<tim> you could try modifying gst/printf/gst-printf.h to #undef HAVE_SNPRINTF
then it might take a different code path
<ds> hrm, ok
<tim> not sure I understand the complaint yet
<ds> that does work around the problem
<tim> not sure if there's anything else we can do
<ds> I can't see how any libc function is called with %n
<tim> vasnprintf.c line 662
<tim> aiui it will do "%whatever%n", arg, &len  to determine the length
<tim> if HAVE_SNPRINTF is not defined, it will do a home-grown method to
determine the max length
