Error when returning &array[index] #1127

cbuttner · 2024-02-13T11:02:09Z

int[*] foo = {1,2,3};
fn int* bar(int index) {
  int* array = &foo;
  return &array[index];
  // This is fine: return array + index;
}

Doesn't compile with:
Error: A pointer to a local variable will be invalid once the function returns. Allocate the data on the heap or temp memory to return a pointer.

Thank you! I'll have a look.

@init

…rides the need for `@` in macro names. Fixes to macro context evaluation. Updated allocator api. Removed install_win_reqs.bat. Deterministic @init for MacOS. Fixed temp memory issue with formatter. Support LLVM 19. Add support to compare bitstructs using == and !=. Support Windows `.def` files. Removed invalid grammar from grammar.y. Support compile time folding of &|^~ for bitstructs. `output` project setting now respected. Fix issue where constants were not properly constant folded. Add temp_push/pop. Aliased declarations caused errors when used in initializers. Fix export output. Fix of const ternary #1118. Fix of $$MODULE in nested macros #1117. Fix debug info on globals. `out` now correctly detects subscript[] use #1116. Lateral implicit imports removed. Default to '.' if no libdir is specified. Improved error messages for `--lib`. Fix raylib snake example. Overzealous local escape check corrected #1127.
