Please test and let me know if this works. Extremely appreciated (and a nice approach indeed, as far as I can see). Now rebuilding a bunch of programs (including the gcc compiler itself) with a gcc which uses the patched musl and so far it seems to work. I guess this exercises malloc quite a bit. (Under the gcc stages rebuilding, the loader is used implicitly and presumably the heap exhaustion is not triggered, this confirms that the patch did not damage the brk mode of operation. The compiler seems otherwise to be capable of building everything I throw at it, while being run via the standalone loder, which previously failed due to "no memory") You saved my day, thanks Rich.
