Typo: "int" should be "in".

The commit message lists three distinct changes: initializing the din/dex
pointers in thread_code.c (the crash fix), adding malloc() NULL checks
in the gen*.c files, and replacing sprintf() with snprintf() across 7
files.

These are independently reviewable and deployable changes. The crash fix
is self-contained in thread_code.c. The malloc checks and the
sprintf->snprintf replacements can be bisected and reverted separately.
Please split into separate patches.

Splitting would also let each patch carry a precise subject. The current
subject names float_trigo, but the changes span bessel/, exp_log/,
iperb/, power/, trigo/, thread_code.c, and main.c.

Verdict - Needs revision
