Visual Fortran Run-Time Errors Page 15 of 48
155¹
severe(155): Array index out of bounds for index nn
FOR$IOS_RANGE2. An array subscript is outside the dimensioned boundaries of that
array. Recompile with the /check:bounds option set.
156¹
severe(156): GENTRAP code = hex dec
FOR$IOS_DEF_GENTRAP. The DIGITAL Fortran RTL has detected an unknown
GENTRAP code. The cause is most likely a software problem due to memory
corruption, or software signalling an exception with an incorrect exception code. Try
recompiling with the /check:bounds option set to see if that finds the problem.
157¹
severe(157): Program Exception - access violation
FOR$IOS_ACCVIO. The program tried to read from or write to a virtual address for
which it does not have the appropriate access. Try recompiling with the /check:bounds
option set to see if the cause is an out-of-bounds memory reference.
This is an operating system error. See your operating system documentation for more
information.
158¹
severe(158): Program Exception - datatype misalignment
FOR$IOS_DTYPE_MISALIGN. The DIGITAL Fortran RTL has detected data that is
not aligned on a natural boundary for the data type specified. For example, a REAL(8)
data item aligned on natural boundaries has an address that is a multiple of 8. To ensure
naturally aligned data, use the /alignment option. For more information on alignment,
see Data Alignment Considerations in the Programmer’s Guide.
This is an operating system error. See your operating system documentation for more
information.
159¹
severe(159): Program Exception - breakpoint
FOR$IOS_PGM_BPT. The DIGITAL Fortran RTL has encountered a breakpoint in the
program.
This is an operating system error. See your operating system documentation for more
information.
160¹
severe(160): Program Exception - single step
FOR$IOS_PGM_SS. A trace trap or other single-instruction mechanism has signaled
that one instruction has been executed.
This is an operating system error. See your operating system documentation for more
information.
161¹
severe(161): Program Exception - array bounds exceeded
