I can confirm this using Ubuntu Jaunty on x86. Trying to set the first point of a spring makes the app freeze and to use 100% cpu. With strace: # strace step ... (Here I try to use a spring) ... clock_gettime(CLOCK_MONOTONIC, {8374, 522494049}) = 0 time(NULL) = 1242117616 time(NULL) = 1242117616 time(NULL) = 1242117616 mprotect(0xac732000, 49152, PROT_READ|PROT_WRITE) = 0 mmap2(NULL, 266240, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0xad969000 mremap(0xad969000, 266240, 524288, MREMAP_MAYMOVE) = 0xac953000 mremap(0xac953000, 524288, 1052672, MREMAP_MAYMOVE) = 0xac4ff000 mremap(0xac4ff000, 1052672, 2097152, MREMAP_MAYMOVE) = 0xac2ff000 mremap(0xac2ff000, 2097152, 4198400, MREMAP_MAYMOVE) = 0xabefe000 mremap(0xabefe000, 4198400, 8388608, MREMAP_MAYMOVE) = 0xab6fe000 mremap(0xab6fe000, 8388608, 16781312, MREMAP_MAYMOVE) = 0xaa6fd000 mremap(0xaa6fd000, 16781312, 33554432, MREMAP_MAYMOVE) = 0xa86fd000 mremap(0xa86fd000, 33554432, 67112960, MREMAP_MAYMOVE) = 0xa46fc000 ^CProcess 7555 detached derosa@bowman:~/Desktop$ I ctrl+c the process as it starts taking all the memory and CPU. It seems that the bug is visible only with Qt 4.5. SVN commit 967684 by ksvladimir: BUG: 189734 Fixed bug in spring rendering code (reproducable only with Qt 4.5). M +1 -1 springgraphics.cc WebSVN link: http://websvn.kde.org/?view=rev&revision=967684 The bugfix is backported to 4.2 and will be available in KDE 4.2.4 (June 3rd). *** Bug 192692 has been marked as a duplicate of this bug. *** |
