[issue42309] BUILD: AIX-64-bit segmentation fault using xlc-v11

Michael Felt added the comment: OK - looking at this again. This looks very similiar to another 'coredump' issue (will have to look for the number later). iirc, when something called 'pgen', or similiar was modified. Here is a lengthy `dbx` dump. If I am reading this correctly, it is 'start

[issue42309] BUILD: AIX-64-bit segmentation fault

Michael Felt added the comment: On a different server, different compiler (xlc-v13, mine is xlc-v11) it gets past this point. So, perhaps it is a compiler issue. As the second system is missing many 64-bit libraries - still cannot build 64-bit Python-3.9. Low priority - imho. --
