I've applied it in git. However... during testing, while the package now builds fine on armhf (and armel amd64 ...), I see it makes valgrind crash on arm64 with: Warning: DWARF2 CFI reader: unhandled DW_OP_ opcode 0x92 valgrind: m_debuginfo/readdwarf.c:2822 (copy_convert_CfiExpr_tree): Assertion 'srcix >= 0 && srcix < VG_(sizeXA)(srcxa)' failed. and likewise this doesn't appear to be a problem with kbtin itself -- it's just a regular C program that does nothing weird. While these bugs are unrelated (other than both being failures due to valgrind not liking new toolchains), it makes no sense to upload the fix right now.

Source: kbtin Version: 2.1-2 Severity: serious Tags: patch User: debian-...@lists.debian.org Usertags: 32bit-stackclash Hi, kbtin currently fails to build from source on armhf. The failure is due to an incompatibility between valgrind and stack-clash-protection on 32bit arm reported upstream at: https://bugs.kde.org/show_bug.cgi?id=479699 While waiting for valgrind to get updated, please cosider addressing the immediate issue by disabling stack-clash-protection on armhf with the following snippet in d/rules: ifeq ($(DEB_TARGET_ARCH),armhf) export DEB_BUILD_MAINT_OPTIONS = hardening=+all,-stackclash else export DEB_BUILD_MAINT_OPTIONS = hardening=+all endif You can find the full build logs at: http://qa-logs.debian.net/2024/01/11/armhf/kbtin_2.1-2_unstable-armhf.log The error is: 3: ==1751922== 3: ==1751922== Process terminating with default action of signal 11 (SIGSEGV) 3: ==1751922== Access not within mapped region at address 0xFEC93DC8 3: ==1751922==at 0x118336: read_rc_file.isra.0 (main.c:301) 3: ==1751922==by 0x10F025: read_rc (main.c:319) 3: ==1751922==by 0x10F025: main (main.c:374) 3: ==1751922== If you believe this happened as a result of a stack 3: ==1751922== overflow in your program's main thread (unlikely but 3: ==1751922== possible), you can try to increase the size of the 3: ==1751922== main thread stack using the --main-stacksize= flag. 3: ==1751922== The main thread stack size used in this run was 8388608. 3: --- "/<>/tests/data/#chr, #ord, #hexord (7-bit ASCII).out" 2022-11-06 21:51:48.0 + Thanks, Emanuele
