Bug ID: 57589
Summary: Linux powerpc -mcpu=native returns pointer to variable
on stack in driver-rs6000.c
Product: gcc
Version: 4.9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: meissner at gcc dot gnu.org
In looking at driver-rs6000.c, I noticed that elf_platform (under Linux) reads
the auxv data structure into an auto array, and then returns a pointer to that
array. It should either make the buffer static, or use xstrdup to get a unique
string.
