SIGSEGV running Elf2 binaries #35367

Zig Version

0.17.0-dev.313+27be3b069

Steps to Reproduce and Observed Behavior

This issue is split out from #35307 (this comment and this comment), because it is a separate issue to the original problem. Latest example by @1off reproduced below.

This seems very similar to #32123. Presumably there's some kind of MappedFile bug which leads to parts of the memory-mapped file not being flushed correctly in some cases?

Unlabeling as "regression" since the similarity between these issues suggests to me that these are the same bug, and that it just happens to be triggered a bit more often now than it used to be.

@1off, sorry for yet another ping, but I might have just figured out what's going on, and since the issue doesn't reproduce for me I'll need you to test the fix for me. Could you apply this patch against master and see if it solves your issue?
