Random crash during compilation #791

Open efeklisov opened 8 months ago

efeklisov commented 8 months ago

I'm trying to integrate CLAD in my project, but I get a seemingly random crash when I do so. CLAD is built from source

https://github.com/efeklisov/LiteRF-RadianceFields/blob/7934405fd2cbb58c12dc073a5aaba6439923bb01/example_tracer/example_tracer.cpp#L253

[ 25%] Building CXX object CMakeFiles/testapp.dir/example_tracer/example_tracer.cpp.o
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace, preprocessed source, and associated run script.

Can you attach the preprocessed files in /tmp/example_tracer-cd5b81.cpp and /tmp/example_tracer-cd5b81.sh. I see you are trying to use enzyme within clad. You can do that by using clad::gradient<clad::opts::use_enzyme>(...).

I'm not really trying to mix them. It's just that Enzyme fails on me as well))
