Bug ID: 68059
Summary: [arm] libgcc uses __write to report error
Product: gcc
Version: 5.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: nsz at gcc dot gnu.org
Target Milestone: ---
this bug was reported on the musl libc list:
http://www.openwall.com/lists/musl/2015/10/22/3
libgcc/config/arm/linux-atomic-64bit.c references __write
in __check_for_sync8_kernelhelper.
__write is not a public abi symbol in libc, libgcc should not
reference it.
the standard way is to use assert, but in this case the error
message seems superfluous: the crash is in a ctor, easily
reproducible.
