uabelho added a comment. Hi,
There seems to be something funny going on with the ClangScanDeps/P1689 <https://reviews.llvm.org/P1689>.cppm testcase added in this patch. It fails randomly for me on top of tree (4ad8f7a189570 <https://reviews.llvm.org/rG4ad8f7a189570dc2560d0efdd05e6a8153313808>). Roughly 1 in 10 runs fail for me. E.g. with a crash like Exit Code: 2 Command Output (stderr): -- PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace. #0 0x00000000004ef8b8 llvm::sys::PrintStackTrace(llvm::raw_ostream&, int) (/repo/uabelho/main-github/llvm/build-all/bin/clang-scan-deps+0x4ef8b8) #1 0x00000000004ed5ae llvm::sys::RunSignalHandlers() (/repo/uabelho/main-github/llvm/build-all/bin/clang-scan-deps+0x4ed5ae) #2 0x00000000004f0096 SignalHandler(int) Signals.cpp:0:0 #3 0x00007f6518263630 __restore_rt sigaction.c:0:0 #4 0x0000000000474f40 P1689Deps::addSourcePathsToRequires() crtstuff.c:0:0 #5 0x00000000004666d1 P1689Deps::printDependencies(llvm::raw_ostream&) crtstuff.c:0:0 #6 0x000000000046204a main (/repo/uabelho/main-github/llvm/build-all/bin/clang-scan-deps+0x46204a) #7 0x00007f6515996555 __libc_start_main (/lib64/libc.so.6+0x22555) #8 0x000000000045fcad _start (/repo/uabelho/main-github/llvm/build-all/bin/clang-scan-deps+0x45fcad) FileCheck error: '<stdin>' is empty.
