Compiler Segfault & Double Free

[jon-lipstate]

Context

In the process of porting a library, I allowed a good number of errors to accrue before bothering to address them. I noticed that >20 errors (guessing) the compiler starts giving Segmentation fault and occasionally Double Free or corruption (out)\n Aborted . I was using odin build . to chase errors and clean them. An additional observation (unrelated (?) ) is that errors were ping ponging locations in the file, eg error on 343, error on 1052, next on 128, next on 744 and so forth.

Operating System & Odin Version:

• Odin: dev-2023-04:0234f50d ( i think i have pulled since i had the errors, but likely exact build is within the last week)
• OS: Windows 10 Professional (version: 22H2), build 19045.2728
• CPU: AMD Ryzen 9 3950X 16-Core Processor
• RAM: 32686 MiB

Failure Information (for bugs)

Please provide detailed steps for reproducing the issue.

I retained a copy of the files that still contains a good number of errors and was producing the error state for me here:
