cnalloc.h bug MRE

RESOLVED!

The key was to link carma to the external library at compile time to avoid the memory allocation function mismatch. See RUrlus/carma#89.

To reproduce:

cmake -S . -B build
cmake --build build
python pymod_test.py

Notes

  • By commenting out #include <carma> in pymod.cpp the bug no longer appears.
  • The bug persists even after avoiding the precompiled cnalloc.h file by using the target carma::headers in CMakeLists.txt, even with the prescribed include order.
  • The program appears to crash only for code compiled in a separate library, not from within the binding module or a header file.
