Hello, I am quite confused with the following behavior of this function: function switchcase(i, str) case = str if uppercase(case) == "A" @info "set case A" showcase(i) = @printf("case A number %i", i) elseif uppercase(case) == "B" @info "set case B" showcase(…

I wandered if this alternative works, in which the functions are defined before and the conditional only assigns a new name, but I get a segmentation fault error. Any comment on that? julia> using Printf julia> showcaseA(i) = @printf("case A number %i", i) showcaseA (generic function with 1 metho…

I was just poking at that — if you remove the @info and @error lines, the segfault goes away.

Actually removing only the @ from @error solves that: julia> showcaseA(i) = @printf("case A number %i", i) showcaseA (generic function with 1 method) julia> showcaseB(i) = @printf("case B number %i and some more parameters %i", i,8) showcaseB (generic function with 1 method) julia> switchcase(2, …

The @error macro makes the error be non-fatal, and the function continues to evaluate the showcase function, which will not be defined in that case. If we add any assignment for showcase after the error, the segmentation fault disappears, and one gets a sensible error message: el…

I’ve filed an issue with Julia that includes the fancy-new --bug-report=rr tracing feature.

[image] lmiq: If we add any assignment for showcase after the error, the segmentation fault disappears, and one gets a sensible error message: … The correct error message should be [an UndefVarError], without the definition of showcase after the error: Yeah, you’re completely right. Also, t…
