the file that stops the compile. Would add the shell file, but can't
My attempt to build world with Current has failed twice when compiling the AMD64 component b_tgamma.c
I don't a backtrace but I have attached the two files the error message requested.
The Error code for this problem is 254.
I will try again tomorrow after updating my sources.
This file hasn't been significantly changed in >10 years. What is the error message you are seeing from the build?
The error messages were the following:
unable to execute command: Bus error (core dumped)
clang frontend command failed due to the signal (use -v to see invocation)
clang version 6.0.0 based on LLVM 6.0.0
[I am not sure how to use -v in order to see invocation. I am currently attempting build world again after refreshing my sources for current]
Bus error on AMD64 really surprises me. The only way I know to get it is accessing past the end of a truncated file via mmap(2). And b_tgamma.c should not be truncated during the build.
CC'ing dim@, who updated the toolchain to LLVM 6.0.0, in case this is a new regression.
Please also attach the .sh file. You can click "add an attachment" just above the main text field to add as many attachments as needed.
That said, is the error repeatable? If you build world a few times, does it always crash at exactly the same place?
My buildworld yesterday failed also, but this time on a different file. The file was entries.c
The error messages were the same. I will attach the sh file for entries.c The sh file for b_tgama-98c0a0.c is gone. I forgot to move it.
The version of clang is release_60 321788
Hope this helps.
I will try to build world again with refreshed sources today.
Sorry. The sh file for entries.c is gone. I guess when I shut down last night it was removed. My build will certainly fail again today and I will send the relevant files before shutting down.
My buildworld failed again at a different place. There was a different error message:
Assertion failed: ((!Ptr || isHandleInSync()) && "handle not in sync"), function operator =, file /usr/src/contrib/llvm/include/llvm/ADT/DenseMap.h line 1121
error: unable to execute command: Abort trap (core dumped)
error: [same as before]
clang version 5.0.1 (tags/RELEASE_501/final 320880 (based on LLVM 5.0.1)

shell file for the file that the compile stopped at (Sema-f016a0.cpp
Is your hardware failing by any chance? Have you tried running memtest86+ or other stress testing tools?
That is possible. I have not tried testing this machine. It has some age on it and I have been having some other problems with this machine. Anyway, I have another newer machine that I can try the build on. Will do that today and report the results. Thanks.
