Bug ID: 21736
Summary: memory read assertion failure with -f a -s 32
Product: lldb
Version: 3.2
Hardware: PC
OS: MacOS X
Status: NEW
Severity: normal
Priority: P
Component: All Bugs
Assignee: lldb-dev@cs.uiuc.edu
Reporter: mjohn...@gmail.com
Classification: Unclassified
Steps to reproduce:
from the terminal:
1. open a binary;
2. breakpoint set -name main
3. r
4. memory read -f a -s 32 `$rbp` `$rbp + 0x30`
Crashes lldb and reports:
Assertion failed: ("GetMax64 unhandled case!" == NULL), function GetMaxU64,
file /SourceCache/lldb/lldb-320.4.156/source/Core/DataExtractor.cpp, line 692.
Abort trap: 6
memory read -f a -s 32 `$rbp` `$rbp + 0x30`
Assertion failed: ("GetMax64 unhandled case!" == NULL), function GetMaxU64,
file /SourceCache/lldb/lldb-320.4.156/source/Core/DataExtractor.cpp, line 692.
Abort trap: 6
Commentary:
the combination -f a -s 32 is probably nonsensical(?) but changing the value of
the rbp offset to, say, 0x10, returns nothing and does not abort with an
assertion failure.
