Comment:

 The log says:

 {{{
 svg_paint.c:42:18: error: call to undeclared library function 'malloc'
 with type 'void *(unsigned long)'; ISO C99 and later do not support
 implicit function declarations [-Wimplicit-function-declaration]
    42 |         char            *id = malloc (length+1);
       |                               ^
 }}}

 This is curious. [wiki:WimplicitFunctionDeclaration Implicit function
 declarations] have been forbidden since Xcode 12 so I expected this to
 have been broken on earlier OS versions already, but our
 [https://ports.macports.org/port/libsvg/details/ port health indicators]
 show successful builds on macOS 14 and earlier. Still, this version of
 libsvg dates back to 2005, so I would not be at all surprised if it
 contained such bugs.
