HL1 crashes after switching between fullscreen/windowed mode #843

Closed dscharrer closed 11 years ago

dscharrer commented 11 years ago

Steps to reproduce:

  1. Go to Optiosns -> Video
  2. Toggle the "Run in a window" checkbox
  3. Click Apply
  4. Boom

The crash happens after the change, so the desired mode will be in effect the next time when starting Half-Life, making this only a minor issue for me

It doesn't seem to be uploading a crash dump:

system information

alfred-valve commented 11 years ago

Can you reproduce this crash when in windowed mode by just changing the resolution you are running at as well?

dscharrer commented 11 years ago

I just checked, and changing the resolution (both in windowed or fullscreen mode) also crashes the game.

alfred-valve commented 11 years ago

Can you post your OS details please, it sounds like something is pinning hw.so open.

Anything else?

Many thanks for porting Half-Life/GoldSrc :)

Ah ha, Gentoo hey. Can you get the crash in GDB again and then post the output of "info sharedlibrary" please.

Hm, it doesn't seem to crash when resizing the window by dragging the corners though, only when changing fullscreen/windowed mode or resolution in the in-game settings.

That line is the problem, something about Gentoo is increasing the refcount on our engine binary, so when we unload it on restart it doesn't actually go away... I'm adding code to try to force the issue, but if you find out why Gentoo causes extra module references that would be interesting.

dscharrer commented 11 years ago

I think I know what is going on:

  1. hw.so exports BZ2_* symbols
  2. hw.so pulls in libfreetype.so.6 and libfontconfig.so.1
  3. On gentoo, both of these are compiled with bzip2 support (in the app-emulation/emul-linux-x86-xlibs-20121202 package)
  4. Because this is still in the dlopen() call for hw.so, the BZ2_* exports in hw.so overwrite those in libbzip2.so (even without RTLD_GLOBAL) and are linked against the BZ2_* imports in libfreetype.so.6
  5. libfreetype.so.6 (and libbzip2.so) now depends on hw.so
  6. hw.so can't be unloaded because libfreetype.so.6 is still used elsewhere

Let me know if you need the full LD_DEBUG=all log - it's over 100 MiB.

readelf confirms the BZ2_* exports in hw.so (note the indices before the symbol names instead of UND for imports):

Everything works on Ubuntu (for now) because their libfreetype.so.6 and libfontconfig.so.1 libraries are compiled without bzip2 support, so the BZ2_* symbols in hw.so aren't used there.

I also confirmed that LD_PRELOADing /lib32/libbz2.so.1 works around the issue by ensuring that the BZ2_* symbols in libbz2 take priority.

The client binaries probably should be compiled with the -fvisibility=hidden gcc flag and then only export the needed symbols.
