Category: vde_switch Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: Nobody/Anonymous (nobody) >Assigned to: renzo davoli (rd235) Summary: malloc assertion fails when vdeterm is run Initial Comment: Hi, I'm using the pdump plugin on vde_switch and use wireshark via cat and ssh to monitor the traffic of the switch remotely. After setting up this monitoring configuration, running "vdeterm /path/to/mgmt_socket" gives the following error: --- VDE switch V.2.2.3 (C) Virtual Square Team (coord. R. Davoli) 2005,2006,2007 - GPLv2 vdeterm: malloc.c:3096: sYSMALLOc: Assertion `(old_top == (((mbinptr) (((char *) &((av)->bins[((1) - 1) * 2])) - __builtin_offsetof (struct malloc_chunk, fd)))) && old_size == 0) || ((unsigned long) (old_size) >= (unsigned long)((((__builtin_offsetof (struct malloc_chunk, fd_nextsize))+((2 * (sizeof(size_t))) - 1)) & ~((2 * (sizeof(size_t))) - 1))) && ((old_top)->size & 0x1) && ((unsigned long)old_end & pagemask) == 0)' failed.

I haven't yet looked into the code much to pinpoint the bug, but I hope this can be fixed.
