Description of problem: I'm having non-abe-specific problems with games that try to use low video modes, probably due to the kernel modesetting work. I ran "abe -t" to find out what modes abe thinks it can use, so I can select one that works. I got a list of modes, followed by this: *** glibc detected *** abe: free(): invalid pointer: 0x0000003157b69ed8 *** ======= Backtrace: ========= /lib64/libc.so.6[0x3157875a26] /usr/lib64/libSDL-1.2.so.0[0x3f1443ee15] /usr/lib64/libSDL-1.2.so.0[0x3f144413ef] /usr/lib64/libSDL-1.2.so.0(SDL_VideoQuit+0x42)[0x3f1442fe12] /usr/lib64/libSDL-1.2.so.0(SDL_QuitSubSystem+0x45)[0x3f144082b5] /usr/lib64/libSDL-1.2.so.0(SDL_Quit+0xe)[0x3f1440834e] /lib64/libc.so.6(exit+0xe2)[0x31578367f2] abe[0x406e0d] /lib64/libc.so.6(__libc_start_main+0xfd)[0x315781ea2d] abe[0x401999] That is followed by a (long) memory map, which I can attach if it is helpful. Version-Release number of selected component (if applicable): abe-1.1-10.fc11.x86_64 How reproducible: Always Steps to Reproduce: 1. abe -t Actual results: Glibc reports free() of an invalid pointer.

Thanks for the report. I'm able to reproduce this locally as well. I'll take some time offline to try to diagnose this.
This message is a reminder that Fedora 11 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 11. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '11'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 11's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 11 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Refiling against F13 so that it doesn't get lost.
I looked at this today. The problem is that the function testModesInFormat() in src/Main.c calls SDL_ListModes(), then passes the result of that function to free(). However, SDL_ListModes() returns a pointer to internal SDL storage. Just get rid of the line: free(modes); on line 39 of Main.c and this problem will go away.
