Bug ID: 112364
Summary: calloc used incorrectly
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libfortran
Assignee: unassigned at gcc dot gnu.org
Reporter: muecker at gwdg dot de
Target Milestone: ---
As detected by -Walloc-size, there are some calls to calloc in libgfortran with
incorrectly ordered arguments.
See: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=112347#c10
../../../trunk.year/libgfortran/io/async.c:265:24: warning: allocation of
insufficient size ‘1’ for type ‘transfer_queue’ with size ‘80’ [-Walloc-size]

transfer_queue *tq = calloc (sizeof (transfer_queue), 1);
Note that for the allocated size the order of arguments does not matter, but -
at least according to my understanding - the alignment requirements for the
returned memory may depend on the object size being the second argument.
