Bug ID: 476535
Summary: Difference in allocation size for
massif/tests/overloaded-new between clang++/libc++ and
g++/libstdc++
Classification: Developer tools
Product: valgrind
Version: 3.22 GIT
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: massif
Assignee: n...@valgrind.org
Reporter: pjfl...@wanadoo.fr
Target Milestone: ---
This allocation
s* pa1 = static_cast<s*>(operator new(sizeof(*pa1),
static_cast<std::align_val_t>(256U)));
causes this output with clang++/libc++
5 16,216 16,216 16,000 216 0
and with g++/libstdc++
5 16,248 16,248 16,000 248 0
(the standard library used shouldn't be a factor as replacement allocators are
used in the main source file).
Previously there were 32 bytes of extra-heap. I'd expect another 8 bytes for
admin, making 40, plus whatever the alignment adds. clang++ adds 176, g++ adds
208.
If this is being rounded up to the next multiple of 256 then I'd expect 96 to
get added.
