No pretty trace if using compressed debug sections

[mathiaswagner]

If I used compressed debug sections (see https://maskray.me/blog/2022-01-23-compressed-debug-sections) I only get outputs like (using test_stacktraceand adding -gz to the cmake configuration for compiling and linking):

Stack trace (most recent call last):

Without the -gz flags everything works as expected and I get the source printed as expected.

Not sure if there is an easy way to fix that.
