Description
c/src/lib/include/rtems/termiostypes.h contains this struct:
struct rtems_termios_rawbuf {
volatile char *theBuf;
volatile unsigned int Head;
volatile unsigned int Tail;
volatile unsigned int Size;
rtems_id Semaphore;
};
When compiling termios.c, gcc warns about discarding qualifiers:
../../../../../../../rtems.work/c/src/lib/libc/termios.c: In function `rtems_termios_close':
../../../../../../../rtems.work/c/src/lib/libc/termios.c:441: warning: passing arg 1 of `free' discards qualifiers from pointer target type
../../../../../../../rtems.work/c/src/lib/libc/termios.c:442: warning: passing arg 1 of `free' discards qualifiers from pointer target type
The relevant parts of termios.c gcc complains about, contain
free(...theBuf).
=> gcc complains about freeing a pointer to volatile memory.
