E.g.
% bin/lldb
../tools/lldb/test/functionalities/breakpoint/breakpoint_conditions/a.out
Current executable set to
'../tools/lldb/test/functionalities/breakpoint/breakpoint_conditions/a.out'
(x86_64).
(lldb) breakpoint set --name c -c 'val == 3'
Breakpoint 1: where = a.out`c + 7 at main.c:36, address = 0x0000000000400667
(lldb) run
Process 27897 launched:
'../tools/lldb/test/functionalities/breakpoint/breakpoint_conditions/a.out'
(x86_64)
Process 27897 stopped

-> 65 {

67 char **argv;
68 char **env;
Stopped due to an error evaluating condition of breakpoint 1.1: "val == 3"
Couldn't execute expression:
Couldn't materialize struct: size of variable val disagrees with the
ValueObject's size (0,4)
Errored out in Execute, couldn't PrepareToExecuteJITExpression
