I can reproduce this issue when compiling for the scumm or scumm_7-8 engines. But this is not a problem with the amiga-gcc toolchain infrastructure. You should move this issue to "gcc" as it is a compiler issue.

scummvm compiles again, but it's not working properly here. Any hints are welcome!

mheyer32 commented 5 years ago

Still fails to compile for me:

Something in the latest gcc patches has fixed the build issue. Was that intended? :-)

... still trying to make it work proper... ... scummvm compiles but it's not ok.

the purpose of commits is to break more than it fixes...
