5 months ago @Neo-Desktop Do you maybe know if this patch still needs to be applied to GCC 12.2.0? That's the latest DJGPP version that build-djgpp supports at this time of writing, but I can't get that version to build on Alpine Linux ether. But I'm not getting a poisoned calloc error. Or at least, that error wouldn't stand out from the log. It's really failing without a clear compile error.
This is the Dockerfile that I wrote that reproduces the build error:

basically its a gcc problem but the djgpp doesn't build under a muslc environment (and therefore alpine linux)
I had to include this patch for it to build correctly
https://gitweb.gentoo.org/proj/gcc-patches.git/tree/12.1.0/musl/50_all_calloc_libgccjit.patch?id=caa4485a49e1064181e7ac2df2c5476fbb6e9cf5
side note- I also prefer to use clang even though I'm not in a freebsd environment. The build script overrides both
CCandCXXeven if I pass it in as an environment variable.the patches below remove the freebsd check and just override the script to use clang and clang++, this is obviously not necessary but it conforms to my usecase
this is the patch set I use to get it to compile correctly under alpine:
