I'm trying to read a file with scm_c_primitive_load() that uses some custom functions defined with scm_c_define_gsubr(). If I pass an invalid data type to one of these functions, I get an expected exception, but the line number of the file where they occur is not included in the stack trace. I tried following the directions in the manual under '6.25.3.2 Capturing the full error stack', and wrapping the call in scm_c_catch(), while manually capturing the stack, but it still doesn't seem to include the line number.
I'm using guile 2.0.14.
