LLDB-17 Crashes with Floating Point Exception When Debugging LLVM-Based Compiler Project #114492

Open ghamarian opened 3 weeks ago

ghamarian commented 3 weeks ago

I’m working on a compiler project based on LLVM and encountering an issue when trying to debug my unit tests using LLDB-17. The debugger crashes with a floating point exception both in VSCode and from the command line. Interestingly, LLDB-17 works fine with another project.

Here are the details of the crash:

EugeneZelenko commented 3 weeks ago

Could you please try 19 or main branch?

ghamarian commented 3 weeks ago

I have tried 18 as well. I give 19 a try.

ghamarian commented 3 weeks ago

I compiled LLDB from the main branch with debug info, and here is the stack trace I get.

@EugeneZelenko any idea if this is an lldb issue or not?

jimingham commented 2 weeks ago

This is crashing reading the relocations for some ELF file. lldb's goal is never to crash even if the object files it is presented with are bogus in one way or another. So this is at least an lldb issue...

OTOH, debugging it with just a stack trace is likely to be difficult. If you can provide an example that causes this crash, it will be much easier to fix.
