I did some more extensive testing, and you are correct. The -mx9 with LZMA sometimes crashes, and other times doesn't with *exactly the same data* attempting to be compressed. So far, I can't point to what causes success and what does not. This also happened with your version of p7zip 4.61 compiled with pthreads... However, the compile of 9.13 seems more stable in general compared to 4.61, although it is some 5 to 10% slower on compressing identical data than 4.61, or Ruguxo's 4.65 compiled without pthreads. Strangely, I get more errors with 9.13 on my 4gb and 8gb systems than my 1gb system, could have to do with CWSDPMI r7 and 4 mb pages? Reverting back to r5 has no effect, though. Will try switching extenders and stubs, but I am not hopeful. Anyway, your efforts at getting a true DOS compile of 9.13 are most appreciated.
