Bug#799586: dosbox: DOSBox quits after starting some games e.g. Screamer Rally
retitle 799586 Screamer Rally, HOMM2: segfault in __ieee754_pow_sse2 tags 799586 patch thanks Hi, Both Screamer Rally and Heroes Of Might And Magic II segfault at the same point: #0 0x75f4e9d8 in __ieee754_pow_sse2 (x=2, y=0.33215) at ../sysdeps/ieee754/dbl-64/e_pow.c:114 #1 0x75f5dec4 in __pow (x=2, y=0.33215) at w_pow.c:27 In HOMM2 it happens at the end of a turn. Presumably other titles are affected too. This seems to be a regression, and current svn of Dosbox does indeed work fine. I did a reverse svn-bisect to find the commit that fixed this and found https://sourceforge.net/p/dosbox/code-0/3674 That commit mentions OSX, but applying it to the Debian package does fix the problem, so I guess 64-bit Linux uses the same code path? I'm not sure if only backporting this single fix is worth it, as it looks like other things have regressed too (the opengl renderer) so maybe an update to current svn is in order?

Bug#799586: dosbox: DOSBox quits after starting some games e.g. Screamer Rally
Package: dosbox Version: 0.74-4+b1 Severity: important Tags: upstream Debian Stretch DOSBox 0.74-4+b1 DOSBox will quit shortly after Screamer Rally starts. This was an upstream regression bug. The bug appeared about a year ago and Screamer Rally ran fine before that. I think there is mention somewhere on SourceForge about this bug and it has been fixed. I have built DOSBox from source (3927) without issue. -- System Information: Debian Release: stretch/sid APT prefers testing APT policy: (500, 'testing') Architecture: amd64 (x86_64) Kernel: Linux 4.1.0-2-amd64 (SMP w/8 CPU cores) Locale: LANG=en_GB.utf8, LC_CTYPE=en_GB.utf8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages dosbox depends on: ii libasound21.0.29-1 ii libc6 2.19-20 ii libgcc1 1:5.2.1-17 ii libgl1-mesa-glx [libgl1] 10.6.3-1 ii libpng12-01.2.50-2+b2 ii libsdl-net1.2 1.2.8-4 ii libsdl-sound1.2 1.0.3-7+b1 ii libsdl1.2debian 1.2.15-11 ii libstdc++65.2.1-17 ii libx11-6 2:1.6.3-1 ii zlib1g1:1.2.8.dfsg-2+b1 dosbox recommends no packages. dosbox suggests no packages. -- no debconf information
