FYI: it appears the checksums need to be updated. The currently available Linux x86_64 package does not match the checksum in the PKGBUILD:
d0d7d7df9d6609e578f85096a755fb8f ...
808190e72ae2059076c2afb8bb3f85cced5b2deb7ce80011d9b88b732d5c3d85 ...
To those getting a segfault: coverity has built their tool using an ancient version of glibc which they statically linked. That glibc was using a deprecated kernel API, which has been disabled (for security reasons) since kernel 4.8. They need to recompile their tool with a more recent version of glibc so that it can be used on modern Linux. They are aware of the issue (they talk about it on the front page of https://scan.coverity.com, although they got confused between sysctl and linux cmdline), but they still haven't done it 2 years later.
In the mean time, the kernel feature can be re-enabled by adding vsyscall=emulate to your Linux command line, although it requires the kernel to be compiled with CONFIG_X86_VSYSCALL_EMULATION=y (which is still the case of the official linux package as of today). You can check that by running zgrep CONFIG_X86_VSYSCALL_EMULATION /process/config.gz.
Am I the only one getting a segmentation fault when running cov-build?
Thanks for maintaining this package!
I'm not sure if it is possible, but it would be nice to see a notice/warning message that the tarball needs to be downloaded manually (perhaps even display the URL?) instead of just a file missing error when the correct tarball is not present on the local system.
Regardless, thanks for maintaining this package.
