Regarding: Xfbdev 4.3.0: SIGILL, Illegal instruction in CopyGC () Email: [EMAIL PROTECTED] ------------------------------------------------------------ XFree86 Version: 4.3.0 (-version doesn't seem to work on Xfbdev) - also happens with 4.2.0.
OS: Linux version 2.4.18-rthal5 Area: Xserver Server: XF86_FBDev Video Card: National Semiconductor XpressGraphics (shared memory) Frame buffer driver from Arcom Controls (the motherboard vendor). Description: Stress-testing our embedded application results in a server crash: $ gdb X -pid=<nnnn> .. (gdb) cont Continuing. Program received signal SIGILL, Illegal instruction. 0x08067f76 in CopyGC () (gdb) bt #0 0x08067f76 in CopyGC () #1 0x0805c6ab in ProcCopyGC () #2 0x0805aabd in Dispatch () #3 0x0804a70d in main () #4 0x4004c9d7 in __libc_start_main () from /lib/libc.so.6 The address in the SIGILL is part-way through an instruction. Any suggestions on how to further characterize or debug this problem would be appreciated.

Repeat By: Repeatable by running our proprietary application with high display update rate for ten minutes or so on an embedded system (National Geode processor, Arcom SBC-GX1 motherboard). Same thing happens if the app targets the X server on another box. Running the same application targetting a desktop X server (RedHat Linux 8.0) it eventually fails with no error message of any kind (probably a different problem, I think). _______________________________________________ XFree86 mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/xfree86
