Description of problem: Running gdb testsuite crashes the machine. Only with kernel patched by the attached patch, though - so feel free to ignore this bugreport. I believe the patch is innocent and just enables the full functionality of ptrace/utrace Linux kernel debugging for gdb. The attached patch should be obsoleted/contained in kernel-2.6.17-1.2633 as announced in Bug 205179. Version-Release number of selected component (if applicable): kernel-2.6.17-1.2630_jkratoch0.ia64 gdb-6.5-7.src How reproducible: It crashed 3 times - each time I tried it. Steps to Reproduce: 1. Install gdb-6.5-7.src.rpm 2. (possibly not needed) patch gdb.spec <http://cvs.jankratochvil.net/viewcvs/nethome/src/gdb.spec-debug.patch?rev=HEAD 3. rpmbuild -bc gdb.spec 4. cd gdb-6.5/gdb/testsuite 5. make check Actual results: Kernel crash. Expected results: No kernel crash, just userland testsuite PASSes/FAILs. Additional info: It was crashing while executing "gdb.base/checkpoint.exp". Removing "gdb.base/checkpoint.exp" testcase made the testsuite non-crashing. Running just specifically "gdb.base/checkpoint.exp" did not crash it, though. -- Additional comment from jkratoch on 2006-09-18 14:00 EST -- Created an attachment (id=136560) [edit] oops log - Unable to handle kernel paging request at virtual address 6b6b6b6b6b6b6b6b -- Additional comment from jkratoch on 2006-09-18 14:01 EST -- Created an attachment (id=136561) [edit] Enable full debugging, should be obsoleted by Bug 205179 -- Additional comment from jkratoch on 2006-09-26 07:02 EST -- Crash again during gdb testsuite: Running ../.././gdb/testsuite/gdb.base/checkpoint.exp ... occured for me today again - but on x86_64. So it is not architecture specific. I do not have the crash dump, though. -- Additional comment from jkratoch on 2006-09-26 07:04 EST -- BTW this time it was stock RawHide: kernel-2.6.18-1.2689.fc6.x86_64 -- Additional comment from jkratoch on 2006-09-27 11:59 EST -- And so far it appears to me the crash is on gdb/testsuite/gdb.base/chng-syms.exp - recompiling of the executable binary while it is still running (and being debugged by gdb).
