Hi,
Sorry if this question comes several times, it seems that for some
reason my emails are not always coming through to the mailing list... So
re-sending.
I started getting this build error from the latest NuttX:
misc/lib_execinfo.c:45:17: error: null argument where non-null required
(argument 1) [-Werror=nonnull]
45 | int ret = sprintf(NULL, "%pS", *buffer++);
| ^~~~~~~
In function 'backtrace_malloc',
inlined from 'backtrace_symbols' at misc/lib_execinfo.c:67:10:
misc/lib_execinfo.c:45:17: error: null destination pointer
[-Werror=format-overflow=]
45 | int ret = sprintf(NULL, "%pS", *buffer++);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
cc1: all warnings being treated as errors
What is the deal with sprintf to NULL ptr?
Thanks,
Jukka
