https://github.com/ArtifexSoftware/ghostpdl/commit/3c0be6e4fcffa63e4a5a1b0aec057cebc4d2562f From 3c0be6e4fcffa63e4a5a1b0aec057cebc4d2562f Mon Sep 17 00:00:00 2001 From: Ken Sharp Date: Wed, 10 Sep 2025 08:55:30 +0100 Subject: [PATCH] Fix 32-bit build Bug #708824 "ghostscript 10.06.0 compilation failure on 32-bit archs" nbytes shiouldn't be an intptr_t, it doesn't get used for pointer arithmetic. Previously it was a uint, should be a int64_t, to fit with all the other devices. Checked other warnings, and found a (very minor) one in gdevdbit.c, fix that while we're here (signed/unsigned mismatch, we don't really care). --- base/gdevdbit.c | 2 +- base/gdevmpla.c | 6 +++--- 2 files changed, 4 insertions(+), 4 deletions(-) diff --git a/base/gdevdbit.c b/base/gdevdbit.c index e07cc3f3b8..1b5c69325b 100644 --- a/base/gdevdbit.c +++ b/base/gdevdbit.c @@ -191,7 +191,7 @@ gx_default_copy_alpha_hl_color(gx_device * dev, const byte * data, int data_x, fit_copy(dev, data, data_x, raster, id, x, y, width, height); row_alpha = data; out_raster = bitmap_raster(width * (size_t)byte_depth); - if (check_64bit_multiply(out_raster, ncomps, &product) != 0) + if (check_64bit_multiply(out_raster, ncomps, (int64_t *) &product) != 0) return gs_note_error(gs_error_undefinedresult); gb_buff = gs_alloc_bytes(mem, product, "copy_alpha_hl_color(gb_buff)"); if (gb_buff == 0) { diff --git a/base/gdevmpla.c b/base/gdevmpla.c index 2f0d522561..ffc5ff42e6 100644 --- a/base/gdevmpla.c +++ b/base/gdevmpla.c @@ -1954,12 +1954,12 @@ mem_planar_strip_copy_rop2(gx_device * dev, int i; int j; intptr_t chunky_sraster; - intptr_t nbytes; + int64_t nbytes; byte **line_ptrs; byte *sbuf, *buf; chunky_sraster = sraster * (intptr_t)mdev->num_planar_planes; - if (check_64bit_multiply(height, chunky_sraster, (size_t *)&nbytes) != 0) + if (check_64bit_multiply(height, chunky_sraster, &nbytes) != 0) return gs_note_error(gs_error_undefinedresult); buf = gs_alloc_bytes(mdev->memory, nbytes, "mem_planar_strip_copy_rop(buf)"); if (buf == NULL) { @@ -2003,7 +2003,7 @@ mem_planar_strip_copy_rop2(gx_device * dev, intptr_t i; intptr_t chunky_t_raster; int chunky_t_height; - intptr_t nbytes; + int64_t nbytes; byte **line_ptrs; byte *tbuf, *buf; gx_strip_bitmap newtex;
