stacktrace: Init elf_fd in sysprof_init_dwfl
|
||
|
||
When building with LTO gcc believes elf_fd can be used uninitialized:
|
||
|
||
In function ‘sysprof_init_dwfl’,
|
||
inlined from ‘sysprof_unwind_cb’ at stacktrace.c:1235:16:
|
||
stacktrace.c:1087:7: error: ‘elf_fd’ may be used uninitialized [-Werror=maybe-uninitialized]
|
||
1087 | close (elf_fd);
|
||
| ^
|
||
|
||
This code won't be reached because if find_procfile doesn't initialize
|
||
elf_fd, it will return an error. But help the compiler by initializing
|
||
elf_fd to -1.
|
||
|
||
* src/stacktrace.c (sysprof_init_dwfl): Init elf_fd to -1.
