Memory leak on task deletion with configUSE_NEWLIB_REENTRANT

[hs2 (Hartmut Schaefer)]

Yes. Or use an alternative printf version without heap usage like this one:

I personally like to use printf-stdarg.c
That implementation is ISR-safe, and it has a small use of the stack. However, it does not implement floating point notations.

Note that other (very few) newlib functions might also dynamically allocate memory internally or do that by definition like strdup.
