Bug ID: 20319
Summary: Crashes on run with Segmentation Fault
Product: lldb
Version: unspecified
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: All Bugs
Assignee: lldb-dev@cs.uiuc.edu
Reporter: peterhul...@gmail.com
Classification: Unclassified
I have installed lldb-3.5 from the ubuntu package repository but it always
crashes when I run the debuggee.
Typical session: (me.c is just 'hello world' - behaviour is the same for any
program)
$ clang -O0 -g me.c -o me
$ lldb me
Current executable set to 'me' (i386).
(lldb) run
Process 13850 launching
Segmentation fault (core dumped)
Reproducible:
always
Using gdb I can get a backtrace:
