--- Begin Message ---Source: cpl Version: 7.0-3 Severity: normal Tags: upstream Hi, I noticed this on Ubuntu, where we build armhf packages on arm64 machines which trigger a SIGBUS on unaligned access. The test cpl_basic_image-test fails: > root@ethical-kitten:~/cpl-7.0# ./libtool --mode=execute gdb > cplcore/tests/cpl_image_basic-test > [...] > Reading symbols from > /root/cpl-7.0/cplcore/tests/.libs/lt-cpl_image_basic-test...done. > (gdb) run > Starting program: /root/cpl-7.0/cplcore/tests/.libs/lt-cpl_image_basic-test > Cannot parse expression `.L954 4@r4'. > warning: Probes-based dynamic linker interface failed. > Reverting to original interface. > > [Thread debugging using libthread_db enabled] > Using host libthread_db library "/lib/arm-linux-gnueabihf/libthread_db.so.1". > > Program received signal SIGBUS, Bus error. > cpl_mask_count_window (self=self@entry=0x35338, llx=<optimized out>, > lly=lly@entry=1, urx=urx@entry=17, ury=15) at cpl_mask.c:1139 > 1139 const size_t countz = *(const size_t*)(pi + i) > (gdb) bt > #0 cpl_mask_count_window (self=self@entry=0x35338, llx=<optimized out>, > lly=lly@entry=1, urx=urx@entry=17, ury=15) at cpl_mask.c:1139 > #1 0xf772397e in cpl_mask_count (in=in@entry=0x35338) at cpl_mask.c:1087 > #2 0x0001e198 in cpl_image_bitwise_test (nx=<optimized out>, ny=<optimized > out>) at cpl_image_basic-test.c:2100 > #3 0x0001234e in main () at cpl_image_basic-test.c:145 This is the code > for (; i < (urx & ~CPL_MASK_PAD2); i+= CPL_MASK_WORD2) { > const size_t countz = *(const size_t*)(pi + i) > + *(const size_t*)(pi + i + CPL_MASK_WORD); I guess this access or the preceeding loop > /* FIXME: Should really ensure byte-wise iteration to word-boundary */ > for (; i < llx - 1 + CPL_MASK_PAD2WORD2(llx - 1); i++) { needs to become aligned, but it's a bit complicated for me to understand as someone new to the codebase. Any ideas? Or could you help & forward upstream please? Thanks, -- Iain Lane [ [email protected] ] Debian Developer [ [email protected] ] Ubuntu Developer [ [email protected] ]
