You might add ``-l log'' here.
I think it is not the cause :-)
Please disassemble your con-ux binary, the instruction at the EIP is important:
objdump -ld 0x00b0dc7f
00b0dc74 <trampoline>: trampoline(): b0dc74: e8 37 00 00 00 call b0dcb0 <int80_warning> b0dc79: 8d 64 24 04 lea 0x4(%esp),%esp b0dc7d: cf iret b0dc7e: 90 nop b0dc7f: 90 nop
But as I have noted, I think the original position of the error is in function sw_fill in pslim.c: ... if (vc->do_drty) vc->do_drty(x, y, w, h); ...
"vc->do_drty" equals 0x00b0d73c here which seems to be invalid. And I guess "new->do_drty" should be initialized to "fg_do_drty" (NULL) in function do_switch in main.c.
