Subject: [PATCH] readelf: Allocate job_data one-by-one as needed
|
||||
|
||||
Currently, job_data is stored in an array whose size is equal to the
|
||||
number of debug sections (.debug_*, .eh_frame, .gdb_index, etc.).
|
||||
|
||||
This size may be too small if a binary contains multiple debug sections
|
||||
with the same name. For example an ET_REL binary compiled with -ggdb3
|
||||
can contain multiple .debug_macro sections.
|
||||
|
||||
Fix this by allocating job_data on the fly when preparing to read a
|
||||
debug section. This supports an arbitrary number of debug sections
|
||||
while also avoiding unnecessary memory allocation.
|
||||
