[Bug c/41311] [4.5 regression] FFmpeg crashes when converting mpg to avi
--- Comment #9 from nospamname at web dot de 2009-09-09 14:54 --- ratecontrol.c line 624 cause crash in my source.assert is done by this command(should be fbngt) FBNLT _ff_rate_estimate_qscale+$716 ;118F015C q= get_qscale(s, rce, rate_factor, picture_number); printf(%f\n,q); // (is 613.928) if (q 0) return -1; TRAP assert(q0.0); the TRAP command is a define to jump in debugger with trap #0.i notice it seem break the peephole detect and so GCC 4.5.0 produce working code when trap is in.see the FBNGT _ff_rate_estimate_qscale+$71A.thats correct and ffmpeg work. on 2. asm snippet that do not work its. and the assert is execute FMOVE.D (A7)+,FP0 FMOVE.S FP0,D4 FMOVE.S D4,FP4 FMOVE.D FP4,-(A7) PEA _ff_get_2pass_fcode+$24(PC) ; JSR _printf ;11A1563C LEA $20(A7),A7 FTST.S D4 FBLT_ff_rate_estimate_qscale+$5D4 TRAP#0 FTST.S D4 FBNGT _ff_rate_estimate_qscale+$71A FMOVE.D FP4,-(A7) MOVE.L A3,-(A7) MOVE.L A2,-(A7) without this asm command trap #0 the asm code that fail.
