Please note that this message will contain a full copy of the comment thread, including the initial issue submission, for this request, not just the latest update. Category: externals Group: v0.43 Status: Open Resolution: None Priority: 5 Private: No Submitted By: Roman Haefeli (reduzent) Assigned to: Nobody/Anonymous (nobody) Summary: zexy's [sgn~] and [abs~] crash
Initial Comment: If DSP is on and DSP graph is recompiled (new tilde object is generated and connected in a patcher window), zexy's [sgn~] and [abs~] do _sometimes_ crash. This happens only on one of two machines with the same version of Pd and zexy installed.
How to trigger the crash: 1) pd -noprefs -lib zexy 2) turn DSP on 3) Create new patcher window (Ctrl-N) 4) Create [abs~], create a [+~] and connect them 5) If it does not crash yet, repeat step 4)
On one of my machines it virtually always crashes on the second iteration.
GDB backtrace (with [abs~]):
Program received signal SIGSEGV, Segmentation fault. sigABS_performSSE (w=0x81a53c0) at abs~.c:58 58 out[0] = _mm_and_ps(in[0] , bitmask); (gdb) backtrace #0 sigABS_performSSE (w=0x81a53c0) at abs~.c:58 #1 0x080dd227 in dsp_tick () at d_ugen.c:336 #2 0x080c7f40 in sched_tick () at m_sched.c:382 #3 m_pollingscheduler () at m_sched.c:482 #4 m_mainloop () at m_sched.c:568 #5 0x080d49ab in main (argc=3, argv=0xbffff734) at s_entry.c:32

This is with / on: - Ubuntu 11.04 i386 - Intel(R) Core(TM)2 Duo CPU T8300 - Pd 0.43.1test2 - zexy from svn r15308
It does _not_ crash on this setup: - Ubuntu 10.04 i386 - Intel(R) Core(TM)2 Duo CPU U9400 - Pd 0.43.1test2 - zexy from svn r15308
