binary ./prev-gcc/d21
version v2.100.1
predefs GNU D_Version2 LittleEndian GNU_DWARF2_Exceptions GNU_StackGrowsDown
GNU_InlineAsm assert D_PreConditions D_PostConditions D_Invariants D_ModuleInfo
D_Exceptions D_TypeInfo all X86 D_HardFloat Posix Solaris CppRuntime_Gcc
So identical to the pre-patch one.
Just in case, here's the stacktrace of the crashing d21, filtered
through c++filt -s dlang:
