Bug ID: 396367
Summary: unhandled syscall amd64-darwin unix:520 and unix:521
Product: valgrind
Version: 3.14 SVN
Platform: Other
OS: OS X
Status: UNCONFIRMED
Severity: crash
Priority: NOR
Component: memcheck
Assignee: jsew...@acm.org
Reporter: gonzalob...@gmail.com
Target Milestone: ---
The jemalloc memory allocator uses the syscalls unix:520 and unix:521 on
macosx, but these are not handled by valgrind. This leads to a lot of warnings
while running the tests under valgrind. This problem is reported in jemalloc
upstream: https://github.com/jemalloc/jemalloc/issues/1274
Also, running jemalloc under valgrind works fine on Linux, but some of the test
crash on MacOSX with a SIGILL. The instruction to reproduce both the warnings
and the crash are in the github issue linked above.
