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 0x00007ffff5f4e9d8 in __ieee754_pow_sse2 (x=2, y=0.33333333333333215) at ../sysdeps/ieee754/dbl-64/e_pow.c:114 #1 0x00007ffff5f5dec4 in __pow (x=2, y=0.33333333333333215) 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?
