This is the fix for RH BZ #981154
|
|
|
7a6771 |
|
|
|
7a6771 |
It is mainly a testcase addition, but a minor fix in the gdb/build-id.c
|
|
|
7a6771 |
file was also needed.
|
|
|

gdb/build-id.c was added by:

and had a little thinko there. The variable 'filename' needs to be set to
|
|
|
7a6771 |
NULL after it is free'd, otherwise the code below thinks that it is still
|
|
|
7a6771 |
valid and doesn't print the necessary warning ("Try: yum install ...").
