Bug ID: 97776
Summary: [C/C++][OpenMP] 'error: array section is not
contiguous in ‘map’ clause' for: map(alloc: p[i][0:C])
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Keywords: openmp
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: burnus at gcc dot gnu.org
CC: cltang at gcc dot gnu.org, jakub at gcc dot gnu.org
Target Milestone: ---
The following is rejected by gcc/g++ with:
error: array section is not contiguous in ‘map’ clause
This map(alloc: p[i][0:C]) is accepted by clang/clang++ and I also do not see
why it is not contiguous.
