Segmentation fault in get_oper #13

Closed ponweist closed 10 years ago

ponweist commented 10 years ago

A segmentation fault occurs when running testcase A of issue #8 with the code verision 37e249c6ff9939e5a2f322cdc10663dc23d7523f.

Running it with the previous version, 0c9e71ec935110e01957884dfa98bfd6c5376323, works.

Reason for segmentation fault was (as reported by enabling runtime checks):

forrtl: severe (408): fort: (7): Attempt to use pointer OO_R when it is not associated with a target

Fixed in 35e705238863b176c6f00f02190413c05da24779. Rerun all testcases - output files seem to be o.k.
