            Bug ID: 202748
           Summary: JSC does not compile on 32bits in Debug mode
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal

          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: pmatos at igalia.com

Since bug 202509 got fixed, we cannot build JSC 32bits in Debug mode.

It fails with:
FAILED: DerivedSources/JavaScriptCore/LLIntAssembly.h

        from /home/pmatos/Projects/igalia/WebKit/Source/JavaScriptCore/offlineasm/asm.rb:376:in `<main>'

In Release mode, JSC builds successfully but a ton of tests fail with a segmentation fault. I am left wondering why the `validate` seems to be happy in Release and raises an error in Debug mode. I am investigating this issue at the moment, but I am happy to discuss possible issues, if anyone has an idea of what is going wrong.
