To Reproduce Steps to reproduce the behavior:

• Install ARM's gcc-arm-none-eabi: https://developer.arm.com/tools-and-software/open-source-software/developer-tools/gnu-toolchain/gnu-rm

• Git check out or extract archive of https://github.com/numworks/epsilon

• Apply the following diff to the above, just in case:

  diff --git a/build/defaults.mak b/build/defaults.mak
  index d8a0c8c0d..f0c03b027 100644

  # This allows the linker script to precisely place a given symbol

• Build the above with make. The result will be in ./output/release/device/n0110/epsilon.elf

• Open the result with Ghidra. I used the "Cortex" Ghidra architecture, as I assume that is short for Cortex-M (the binary is cortex-m7), but I have to say, just "Cortex" is a horrible name as the user can not know what it means, it is not specific enough.

• Auto-analyse. (I set all decompiler deadlines that are "60" by default to "600000").

• Read errors about symbols not being successfully demangled.

• Note that a lot of symbols are, in fact, demangled.

Expected behavior All symbols compiled with GCC/g++ should be demangled.

Environment (please complete the following information):

• OS: ArchLinux (a rolling-release Linux distribution: means all packages are up to date and the Linux kernel is used)
• Java Version: 11.0.6.u10
• Ghidra Version: 9.1.1+r468+gd66027e2

Note that it may be possible to get the same errors after building a "simulator" build for Epsilon, instead of cross compiling: that way it would not be necessary to install ARM's toolchain. But I have not tried yet.

Like this: make PLATFORM=simulator.

This is likely reproducible by demangling the mangled symbols in the provided errors. This is a class cast exception. It appears something is attempting to cast a function to a Structure. Providing the application.log may prove helpful.

[astrelsky]

@astrelsky Can you tell me more about that application.log? How do I find it so I could post it here?

Sure. In linux it should be in ~/.ghidra/{ghidra version} on windows it's in the user directory %HOMEPATH%\.ghidra\{ghidra version}

application.log

For what it is worth: "2020-02-25 12:26:22" seems to be the start of Ghidra's last run.

[dragonmacher]

Many of the failing symbols contain lambda function names, such as: {lambda(char const*, Poincare::Context*)#2}

I am working on updating the parser to handle lambdas. It is not clear if this will fix the ClassCastException you are seeing. Unfortunately, that exception in the log does not contain a line number or stack trace. I will use the samples you have provided above to attempt to reproduce the issue.
