If your LibRaw is older consider upgrade via github (or just apply this patch)
The easiest way to build 32-bit LibRaw for windows is
1) start Visual Studio developer shell in 32 bit mode
(e.g: run cmd.exe and execute
call "C:\Program Files ... path to VisualStudio installation...\VC\vcvarsall.bat" x86
)
2) run nmake -f Makefile.msvc to build LibRaw
32-bit windows (and even more broadly, 32-bit apps) don't look relevant in 2022, nevertheless, it is still too early to completely stop 32-bit systems support.
Could you please provide the sample file that is handled wrong in 32-bit mode? Use info@libraw.org for that :)
On Nov 26, 2021 we fixed one 32-bit related error via this commit: https://github.com/LibRaw/LibRaw/commit/30595a731f3bea78f0410426b73ef3af...
Probably it will fix the issue but we need sample file to be sure.
