Hi mfvalin,

Thanks for the report. I was able to reproduce the error here and have filed TPR #34291. It appears to me to be an issue with using C_PTR in the transfer statement, but will have our engineers investigate.

thank you for your quick answer,
i also reported the problem to AMD (4.1.0 aocc compilers)
as nvfortran’s cousin flang suffers from the same ailment

FYI, TPR #34291 should be fixed in our 24.1 release.

Fails in 23.11 but compiles with 24.1:

% nvfortran -c -V23.11 test2.F90
NVFORTRAN-S-0000-Internal compiler error. select_rtemp: bad ili       0  (test2.F90: 18)
NVFORTRAN-S-0000-Internal compiler error. exp_call: ili ret type not cased       3  (test2.F90: 18)
  0 inform,   0 warnings,   2 severes, 0 fatal for problem
% nvfortran -c -V24.1 test2.F90
