Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jakub at gcc dot gnu.org --- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> 2012-08-23 23:54:24 UTC --- The warning is correct, %as (the oldish GNU extension) clashes with ISO C99 a modifier for hex floats, if you want to allocate memory, use %ms instead, which is the standard way of doing the same.
