Debugging failures during elf loading

[christian-herber-nxp]

I am currently facing a fail during loading of an elf file, and I have a hard time understanding what the issue could be.
In general, slightly more explicit error messages would be nice, but for that one has to understand the code.
My error is thrown on that condition in pk/elf.c:

size_t phdr_size = eh.e_phnum * sizeof(Elf_Phdr);
if (phdr_size > info->phdr_size)

I would appreciate if somebody has input as to what this indicates.

There's a data structure that holds the program headers and is statically sized:

riscv-pk/pk/pk.c

Line 231 in abadfdc

static long phdrs[128]; // avoid large stack allocation

You could probably increase it without consequence. But I agree the error message could be clearer in this case, since this error is not about a malformed ELF, but about a pk constraint.
