Hi!

I'm completely out of my depth on this one, and I wonder whether
anyone might be able to help.

I have just updated pydevd from 2.9.6+ds-1, uploaded 2023-06-23, to
version 2.10.0+ds-1. But the build of the cython extension now fails
on alpha: near the end of the build log

https://buildd.debian.org/status/fetch.php?pkg=pydevd&arch=alpha&ver=2.10.0%2Bds-1&stamp=1697725269&raw=0

is the failed build:

I have no idea what caused these errors. The cython code
(pydevd_cython.pyx) has not changed between these two upstream
versions, and I regenerate the pydevd_cython.c file at this point
(using the --force-cython flag) - as cython3 has not changed, the
resulting C file should not have changed either. So I can only
presume that it is something to do with a change in the C
compiler/linker toolchain.

Any suggestions would be welcome! In the meantime, I can just disable
the cython extension on alpha.

Best wishes,

Julian
