Summary: LLVM JIT crashes on Windows when built in debug mode
Product: new-bugs
Version: 3.9
Hardware: PC
OS: All
Status: NEW
Severity: release blocker
Priority: P
Component: new bugs

CC: llvm-bugs@lists.llvm.org
Classification: Unclassified
Hi,
We found at work, that LLVM JIT engine crashes on Windows 10 when built in
debug mode.
The Windows debug mode sets junks value in memory and LLVM ends with junk
pointers when clearing up its intrusive linked lists.
Here is a stack trace:

I hope I provided enough information.
Thank you for your investigation!
