Bug ID: 27563
Summary: crashlog.py leads to a segfault
Product: lldb
Version: unspecified
Hardware: Macintosh
OS: MacOS X
Status: NEW
Severity: normal
Priority: P
Component: All Bugs
Assignee: lldb-...@lists.llvm.org
Reporter: antonio.frighe...@studenti.unitn.it
CC: llvm-bugs@lists.llvm.org
Classification: Unclassified
Let's say a crash dump has an unspecified stack frame, like the following:
5 ??? 0x00007fff9a51076f objc_exception_throw + 432
Then, once set up lldb and imported crashlog.py script (alternatively via
PYTHONPATH=/path/to/LLDB.framework/Resources/Python ./crashlog.py
~/Library/Logs/DiagnosticReports/a.crash), after being loaded, line 867:
images = crash_log.find_images_with_identifier (ident)
seems to lead to a segmentation fault. Tested on multiple crashes. Looks like
as if a little fix may be as follows:
...
for ident in crash_log.idents:
if ident != "???":
images = crash_log.find_images_with_identifier(ident)
if images:
...
Bye, Antonio.
