ifx: catastrophic error: Statement too long; token limit is 41000.

Hi guys,

In our program, we have a large static array for precomputed coefficients of series for gamma function approximation (also known as Boys functions).

integer, public, parameter :: npf = 450
integer, public, parameter :: ngrd = 7
integer, public, parameter :: ntx_al = 7
real(kind=8), public, parameter :: fgrid(0:ntx_al,0:npf,0:ngrd) = reshape([ &
0.1000000000000002D+01, -0.1944677204778938D-01, 0.3403592489727661D-03, &
...
0.0000000000000000D+00 ], shape=[ntx_al+1, npf+1, ngrd+1])

Both, ifx and ifort (IFX 2023.02) failed to compile the whole file (see the attachment) with the error: `catastrophic error: Statement too long; token limit is 41000.` The whole size of the array is 225 kB in memory.

What is the proper way to initialize such large arrays in compile time?

The limiting factor is not the size of the array. It's the number of continuation lines, the statement length.
