On update from lldb 16 to 18 I observe that summary strings that include the documented bitfield syntax no longer parse, reporting _"error: summary string parsing error"_ instead.
Taking the example directly from the [documentation](https://lldb.llvm.org/use/variable.html#bitfields-and-array-syntax), and a vanilla instance of `lldb`
> lldb --no-lldbinit
>> expr 1234.f # Prints OK
(float) $0 = 1234
>> type summary add --summary-string "Sign: ${var[31]%B} Exponent: ${var[30-23]%x} Mantissa: ${var[0-22]%u}" float
>> expr 1234.f
(float) $1 = 1234 error: summary string parsing error
This was working fine with lldb 16. The above was tested with lldb version 18.1.6 packaged for Fedora 40.
