[Python-Dev] Strange compiler crash in debug builds.

[Mark Hammond]

Something strange is happening in my Windows Debug builds (fresh CVS tree)

If you remove "urllib.pyc", and execute 'python_d -c "import urllib"',
Python dies after printing the message:

FATAL: node type 305, required 311

It also happens for a number of other files (compileall.py will show you
:-)

Further analysis shows this deep in the compiler, and triggered by this
macro in node.h:

---
/* Assert that the type of a node is what we expect */
#ifndef Py_DEBUG
#define REQ(n, type) { /*pass*/ ; }
#else
#define REQ(n, type) \
	{ if (TYPE(n) != (type)) { \
	    fprintf(stderr, "FATAL: node type %d, required %d\n", \
		    TYPE(n), type); \
	    abort(); \
	} }
#endif
---

Is this pointing to a deeper problem, or is the assertion incorrect?

Does the Linux community ever run with Py_DEBUG defined?  I couldn't even
find a simple way to turn it on to confirm it also exists on Linux...

Any ideas?

Mark.
