Issue 1326406: pdb breaks programs which import from main (original) (raw)

The following example illustrates the problem:

bagira:~/python/dist/src/Lib> cat tt/xx hello=None import yy print "in xx:yy imported"

bagira:~/python/dist/src/Lib> cat tt/yy.py from main import hello print "in yy: yy imported "

this works by itself:

bagira:~/python/dist/src/Lib> ../python tt/xx in yy: yy imported in xx:yy imported

But breaks under pdb

bagira:~/python/dist/src/Lib> ../python -m pdb tt/xx
