When debugging a bash shell with its debuginfo loaded on my x86/F7 system, the debug window aborts when you hover over a variable in the source view of shell.c(usually frame #14 on this arch). This works fine on my AMD64/FC6 machine. No backtrace is given. All I get is "Aborted (core dumped)". (This is when I have "ulimit -c unlimited" set in the bash shell where I activate the Frysk UI.) Using "fstack" on the core file I get the following: Task #25147 #0 0x00220802 in [unknown] from /usr/lib/libgtkjava-2.8.so #1 0x00000000 in [unknown] from Unknown Task #25148 #0 0x00220802 in [unknown] from /usr/lib/libgtkjava-2.8.so #1 0x00000000 in [unknown] from Unknown Task #25149 #0 0x00220802 in [unknown] from /usr/lib/libgtkjava-2.8.so #1 0x00000000 in [unknown] from Unknown Using gdb to look at the backtrace I get this: (gdb) bt #0 0x00110402 in __kernel_vsyscall () #1 0x4a950fa0 in ??

When running with strace I get the following: tkill(25288, SIGIO) = 0 futex(0x9212d80, FUTEX_WAIT, 10343, NULL) = 0 futex(0x9212dac, FUTEX_WAKE, 1) = 0 --- SIGSEGV (Segmentation fault) @ 0 (0) --- rt_sigprocmask(SIG_UNBLOCK, [SEGV], NULL, 8) = 0 rt_sigprocmask(SIG_UNBLOCK, [ABRT], NULL, 8) = 0 tgkill(25286, 25286, SIGABRT) = 0 --- SIGABRT (Aborted) @ 0 (0) --- +++ killed by SIGABRT (core dumped) +++ Process 25286 detached ftrace aborted when I tried to use it. If no bug is filed for it, I will file one.
Fixed. Cannot reproduce in a current HEAD checkout.
