Re: Fwd: A: a new bug to old plain C

[ANDREY TARASEVICH via Gcc]

There's no bug in what you posted. Conversition from 'T **' to 'const T *const 
*' has never been allowed as an implicit conversion in standard C (as opposed 
to C++, which allows this). A compliant C compiler should issue a diagnostic 
for this code since this is a constraint violation, which is exactly what your 
compiler did.
 
If I'm not mistaken, C23 is/was supposed to bring C on sync with C++ wrt this 
matter.
