[issue35534] SIGSEGV in stackdepth_walk

[anthony shaw]

anthony shaw <anthony.p.shaw at gmail.com> added the comment:

stackdepth_walk no longer exists in Python 3, this is a 2.7 specific issue.

opcode_stack_effect in compile.c will have the expected stack effect. If there is a mismatch between the Opcodes compiled with the distribution and the ones in the compile.c opcode_stack_effect, it can cause a crash.

Ensure that `make regen-all` is run before compiling with a clean build to avoid this.
