Bug ID: 466104
Summary: aligned_alloc problems, part 1
Classification: Developer tools
Product: valgrind
Version: 3.21 GIT
Platform: Other
OS: All
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: jsew...@acm.org
Reporter: pjfl...@wanadoo.fr
Target Milestone: ---
There are several issues with the handling of memalign, posix_memalign and
aligned_alloc, mostly on non-Linux-glibc systems.
Some arguments are missing TRIGGER_MEMCHECK_ERROR_IF_UNDEFINED
memalign does not set errno correctly
The posix_memalign wrapper just calls the memalign one. That adds noise to the
callstacks and makes it difficult to cutomize behaviour for different
platforms.
memcheck/tests/memalign2.c fails with an assert on at least FreeBSD
I've mostly been looking at glibc musl and FreeBSD / memalign and
posix_memalign
I'll look more at Solaris (Darwin if I can) / aligned alloc.
