[cfe-users] How to enable Initialization Order Fiasco sanitizer from the command line?
Hi Everyone, We have a C++ library and a test script that grinds though various configurations. It include various sanitizers. The script is a security gate, and the self tests must pass for a release. I want to add the Initialization Order Fiasco sanitizer as a command line option, and not a envar export. There are some reasons for it, like a positive confirmation the option exists and explicit invocation of the checker. How do I enable Initialization Order Fiasco sanitizer from the command line? Thanks in advance. ___ cfe-users mailing list cfe-users@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-users
Re: [cfe-users] How to enable Initialization Order Fiasco sanitizer from the command line?
To quote Reid's response from another group:
"""
If you want to bake in some options at compile time, there are a few ways
to do it. -DASAN_DEFAULT_OPTIONS=check_initialization_order=true will work,
or you can define the __asan_default_options function somewhere in the
binary like this:
extern "C" const char *__asan_default_options() { return
"check_initialization_order=true"; }

[cfe-users] segmentation fault 11 when running clang-tidy
I am on Mac OS X 10.11.1, and downloaded the sources and followed the instructions to build clang-tidy. I used xcodebuild and xcpretty to generate the compile_commands.json file. I have the json file in my project root, and ran: ~/build/bin/clang-tidy ./MyFile.m Initially I got this error "LLVM ERROR: unknown module format", and after some Googling, tried to delete all the fmodule and gmodule parameters from the json file. After that, I keep getting "Segmentation fault: 11" most of the time. There was once when I was able to get the list of warnings, but when I run the same command right after, I get the segmentation fault again. Thanks, Hongping ___ cfe-users mailing list cfe-users@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-users
Re: [cfe-users] segmentation fault 11 when running clang-tidy
I tried running the command on some other files, and managed to get it working once, and then it segfaulted again when I ran the same command right after. Suppressed 217 warnings (217 in non-user code). Use -header-filter=.* to display errors from all non-system headers. hongping@HLim-MBP:~/my/project$ ../build/bin/clang-tidy -checks=* ./MyFile.m clang-tidy(3670,0x7fff71f9b000) malloc: *** error for object 0x7fcf2007: pointer being realloc'd was not allocated *** set a breakpoint in malloc_error_break to debug Abort trap: 6 On Mon, Jan 11, 2016 at 5:57 PM, Hongping Lim wrote: > I am on Mac OS X 10.11.1, and downloaded the sources and followed the > instructions to build clang-tidy.
