# patch to fix printf when register_printf_function is in use and the format to
|
|
# printf contains more than 64 elements.
|
|
#
|
|
# extend_alloca modifies nspecs_max (2nd arg) with the size of the space, not the
|
|
# number of elements. Use a temporary to store the return value. Explicitly set the correct size.
