Same as #1543

@nodece Does pulsarctl must be built with CGO_ENABLED=0 ?

@nodece `go test -race` is only called in the test environment, do we have to check gcc since the CI passed (which means a C/C++ compiler is obviously available) ?...

@jim3ma Please note the goroutine in the backtrace: ``` Goroutine 50 in state select, with d7y.io/dragonfly/v2/pkg/rpc.(*Connection).startGC on top of the stack: goroutine 50 [select]: d7y.io/dragonfly/v2/pkg/rpc.(*Connection).startGC(0xc0002f6000) /home/yuanting/work/dev/goprojects/dragonfly/pkg/rpc/client_util.go:45 +0x397 created by d7y.io/dragonfly/v2/pkg/rpc.NewConnection...

Of course, the output is ``` $ umask 0022 ```

@yuleisui I find that variadic arguments have been handled in the SVF [here](https://github.com/SVF-tools/SVF/blob/5612800897b5dc8773504a290dac84a2fd61642d/svf/lib/WPA/Andersen.cpp#L758). Is it safe to remove [this condition](https://github.com/SVF-tools/SVF/blob/5612800897b5dc8773504a290dac84a2fd61642d/svf/lib/MemoryModel/PointerAnalysis.cpp#L413) directly so we can connect variadic functions in the call...

@yuleisui Thanks for the explanation, but the following scene confuses me (I hope `%1` can resolve to `@bar`) ``` ; ModuleID = './test/InitExtFnPtr.bc' source_filename = "./test/InitExtFnPtr.bc" @fnptr = global i32...

Sure, PTAL https://github.com/SVF-tools/SVF/pull/1031

@xudon9 @yuleisui Any update here, please?

@yuleisui Could SVF analyze multiple bitcodes at the same time? I tried this [example](https://llvm.org/docs/LinkTimeOptimization.html#example-of-link-time-optimization) by ``` ../svf-latest/Debug-build/bin/wpa -ander a.bc main.bc ``` but SVF aborted at: ``` ../svf-latest/svf-llvm/include/SVF-LLVM/LLVMModule.h:198: SVF::SVFFunction* SVF::LLVMModuleSet::getSVFFunction(const Function*)...
