<pre>attempting to drill into some global variable state:
lhe.h extern SYSBLK *sysblk;
sysblk.c SYSBLK *sysblk;
I hit the following MapImported assertion:
(lldb) p &sysblk->regs[0]
lldb: /home/pjoot/chirag/llvm-project/clang/lib/AST/ASTImporter.cpp:9444:
clang::Decl* clang::ASTImporter::MapImported(clang::Decl*, clang::Decl*):
Assertion `(Pos == ImportedDecls.end() || Pos->second == To) && "Try to import
an already imported Decl"' failed.
PLEASE submit a bug report to <a href="https://bugs.llvm.org/">https://bugs.llvm.org/</a> and include the crash
backtrace.
