I updated GCC to version 14.2.0, and got another error for the code in the
first post (compiled with `-O0 -g`):
```
In file 'a.f90', around line 8: Error allocating 17510029503779062109 bytes:
Cannot allocate memory
Error termination. Backtrace:
#0 0x400858 in p
at a.f90:7
#1 0x4009d1 in main
at a.f90:7
```
And sometimes this error:
```
Program received signal SIGSEGV: Segmentation fault - invalid memory reference.
Backtrace for this error:
#0 0x7f80f4a42b7f in ???
#1 0x400810 in p
at a.f90:7
#2 0x4009d1 in main
at a.f90:7
Segmentation fault (core dumped)
```
It's not deterministic.
