commit 121a8d0507522dfb7bfd05fc001b0f322c3f9000
Author: Jean-Marc Lasgouttes <[email protected]>

Avoid gcc warning about casting away const
The warning (spotted by Scott) is :
src/support/lassert.cpp:145:22: warning: cast from type ‘const char*’ to
type ‘void*’ casts away qualifiers [-Wcast-qual]
145 | free((void*)demangled);
| ^~~~~~~~~~~~~~~~
Actually the return value of __cxa_demangle is not const. With this
change, the (void*) cast is not needed anymore.
