Hi.
Just for the record, after the change 526.blender_r fails due to:
blender/source/blender/blenlib/intern/math_color.c: In function
'rgb_float_to_uchar':
blender/source/blender/blenlib/BLI_utildefines.h:251:22: error: conversion from
'float' to 'unsigned char' may change value [-Werror=float-conversion]
251 | #define FTOCHAR(val) ((CHECK_TYPE_INLINE(val, float)), \
| ^
blender/source/blender/blenlib/BLI_utildefines.h:257:13: note: in expansion of
macro 'FTOCHAR'
257 | (v1)[0] = FTOCHAR((v2[0]));
\
| ^~~~~~~
blender/source/blender/blenlib/intern/math_color.c:421:2: note: in expansion of
macro 'F3TOCHAR3'
421 | F3TOCHAR3(col_f, r_col);
| ^~~~~~~~~
where the project sets -Werror=float-conversion dues to:
$ cat blender/source/blender/blenlib/BLI_strict_flags.h
#ifdef __GNUC__
# if (__GNUC__ * 100 + __GNUC_MINOR__) >= 406 /* gcc4.6+ only */
# pragma GCC diagnostic error "-Wsign-compare"
# pragma GCC diagnostic error "-Wconversion"
# endif
