Jl.eval-ing an undefined symbol crashes MATLAB in Ubuntu #6

Closed twadleigh closed 8 years ago

twadleigh commented 9 years ago

In https://github.com/twadleigh/jlcall/issues/5#issue-110225788 @bermanmaxim reports:

Hello, Jl.eval exception handling does not work for me under ubuntu, a simple Jl.eval('foobar') crashes Matlab.

However, in windows I get:

>> Jl.eval('foobar')
Error using jlcall
UndefVarError: foobar not defined

Error in Jl.eval (line 21)
          v1 = Jl.mex('mex_eval', e1);

as expected.

This is a more general issue: julia error reporting crashes MATLAB on Ubuntu. If I comment out the call to ccall on error, and make the error output to the terminal instead, Matlab doesn't crash, it only complains that jlcall does not assign an output.

One or more output arguments not assigned during call to "jlcall".

Error in Jl.eval (line 21)
          v1 = Jl.mex('mex_eval', e1);
