Bug#1042376: digikam crashes with "Illegal instruction"

Show all headers | View raw

   Hi Steve,

dm@fluke:/tmp$ g++ matrixtest.cc -I /usr/include/x86_64-linux-gnu/qt5 -msse2 -msse4.1 -fPIC -lQt5Core
dm@fluke:/tmp$ ./a.out
Hello

   Hm.

   Just to be sure, I also ran the attached executables, however they are giving me the same result:
dm@fluke:/tmp$ ./test-sse4
Hello
dm@fluke:/tmp$ ./test-no-sse4
Hello

dm@fluke:/tmp$ g++ --version
g++ (Debian 13.2.0-1) 13.2.0
(...)

   However:
