Good evening,
Building and checking Chicken 4.12.0 RC2 on HP EliteBook running Windows 10
With older MinGW and PLATFORM=mingw : builds successfully and checks run without errors. Well, at the end, it complained about the local repository but I did not write that down. It seemed innocuous.
With current MinGW-w64 and PLATFORM=mingw-msys : builds successfully and checks die with the same error as 4.11.
[panic] invalid encoded numeric literal - execution terminated
