Segfaults when printing strings that have python values

Describe the bug
I have stumbled on many cases where when there is code that is trying to create a string with interpolated python values in it, a segfault can happen.

I don't have a clear way to reproduce the issue, this a stack trace when it happens, trying to log an exception:

XXX lineno: 85, opcode: 150

[20931] signal (11.1): Segmentation fault

It's hard to say much without code that can reproduce the error - please try to figure out a minimal way to make this problem occur.

Some possible causes (not sure if they can actually happen though):

• String interpolation causes some voodoo macro compilation that puts python references in the compiled code
• It's not strings, maybe Revise is deleting some methods that trigger python GC and frees python values still used by other compiled methods

I don't think these are solvable or caused by pythoncall
