Subject: [PATCH] lib: Correct the syntax for gdb backtrace command
|
|
|
10661d |
|
|
|
10661d |
abrt-action-generate-backtrace generates backtraces with error message:
|
|
|
10661d |
A syntax error in expression, near `full'.
|
|
|
10661d |
|
|
|
10661d |
According to the GDB documentation the correct syntax for backtrace
|
|
|
10661d |
command is:
|
|
|
10661d |
backtrace [n]
|
|
|
10661d |
backtrace full [n]
|
|
|
