Greetings,

With -O0 (disabled optimizations) now the building process moved from
"raw_pre_gcl" to "saved_pre_gcl", and then crashed again with a "symbol
not found in flat namespace".  Now this looks like a fixable linking
issue, perhaps related to the new clang compiler on Sonoma w.r.t Catalina.

No useful information if I try to print a backtrace:

What does "flat namespace" mean? Is GCL's C code being (wrongly)
considered/handle as C++ code and is somehow miscompiled due to the new
C++ standard?

Hope this helps,
