Description jaybhaskar 2023-06-23 06:28:08 PDT 
MiniBrowser crashes on startup giving the following call stack

 [libsystem_platform.dylib+0x3748]  _platform_memmove+0xa8
  _platform_memmove+0xa8
   JSC::LinkBuffer::linkCode(JSC::MacroAssembler&, JSC::JITCompilationEffort)+0x40
  WebCore::SelectorCompiler::SelectorCodeGenerator::compile(JSC::MacroAssemblerCodeRef<(WTF::PtrTag)53711>&)+0xe8

is there some recent change in JavaScripCore?

Could you please clarify how you build and run MiniBrowser on device? This is not a common workflow, and I don't think that we have any documentation for it.

Somehow in my system in the file wtf/PlatformUse.h USE_PTHREAD_JIT_PERMISSIONS_API becomes disabled. that was the reason to crash. Thamks.
