After upgrading to glibc-2.2-5, I get sigsegv's with programs that worked fine with glibc-2.1.96. For example, rxvt-2.6.3-2 now always fails if I select text in it and paste it to _another_ window. The same rxvt binary worked with glibc-2.1.96. Unfortunately, I can no longer get a gdb traceback from the rxvt. I got bt's at one point, but now X seems to always kill it before it segfaults: rxvt: XError: Request: 18 . 0, Error: 16 However, the backtrace was similar to this Opera one: 0x4021ef91 in chunk_alloc (ar_ptr=0x402c1c60, nb=16) at malloc.c:2771 2771 malloc.c: No such file or directory. (gdb) bt #0 0x4021ef91 in chunk_alloc (ar_ptr=0x402c1c60, nb=16) at malloc.c:2771 #1 0x4021ed8e in __libc_malloc (bytes=12) at malloc.c:2704 #2 0x400a4a0d in __builtin_new (sz=12) from /usr/lib/libstdc++-libc6.1-1.so.2 #3 0x824fd03 in strcpy () at ../sysdeps/generic/strcpy.c:31 #4 0x8250875 in strcpy () at ../sysdeps/generic/strcpy.c:31 #5 0x8292ad1 in strcpy () at ../sysdeps/generic/strcpy.c:31 #6 0x830288e in strcpy () at ../sysdeps/generic/strcpy.c:31 #7 0x8142c44 in strcpy () at ../sysdeps/generic/strcpy.c:31 #8 0x86a8930 in ?? () (Opera has also begun to segfault at start after glibc upgrade). I compiled rxvt-2.6.3 from source, and it exhibits the same behaviour. Devel version 2.7.2 does not crash, but it corrupts the selection. Other X programs still work fine wrt X selection.
