Bug ID: 51685
Summary: Crash evaluating expression
Product: lldb
Version: unspecified
Hardware: PC
OS: Linux
Status: NEW
Severity: release blocker
Priority: P
Component: All Bugs
Assignee: lldb-dev@lists.llvm.org
Reporter: l...@martijnotto.nl
CC: jdevliegh...@apple.com, llvm-b...@lists.llvm.org
When using lldb, it always fails evaluting an expression. Other things work
normally, I can set breakpoints, and they're correctly triggered, but doing
anything like `p something` always fails, no matter where in the program I do
it or what the expression is. The stack trace:
error: need to add support for DW_TAG_base_type 'auto' encoded with DW_ATE =
0x0, bit_size = 0
PLEASE submit a bug report to https://bugs.llvm.org/ and include the crash
backtrace.
Stack dump:
0. Program arguments: lldb ./build/Debug/Arena
1. HandleCommand(command = "p getServer()")
2. :43:16: current parser token '$__lldb_expr'
