Bug ID: 15817
Summary: [i386] longjmp error in Python call
catch_command_errors
Product: gdb
Version: HEAD
Status: NEW
Severity: normal
Priority: P2
Component: symtab
Assignee: unassigned at sourceware dot org
Reporter: jan.kratochvil at redhat dot com
Host: i386-unknown-linux-gnu
Target: i386-unknown-linux-gnu

Any recent i386 Fedora:

call catch_command_errors(execute_command, "python print 5", 0,
RETURN_MASK_ALL)
Warning:
Cannot insert breakpoint 0.
Error accessing memory address 0xa1900bbf: Input/output error.

../nptl/sysdeps/pthread/pt-longjmp.c:25
25 {
The program being debugged stopped while in a function called from GDB.
Evaluation of the expression containing the function
(catch_command_errors) will be abandoned.
When the function is done executing, GDB will silently stop.
(gdb) FAIL: gdb.gdb/python-selftest.exp: call
catch_command_errors(execute_command, "python print 5", 0, RETURN_MASK_ALL)

Moreover occasionally:

call catch_command_errors(execute_command, "python print 5", 0,
RETURN_MASK_ALL)
infrun.c:5514: internal-error: insert_longjmp_resume_breakpoint: Assertion
`inferior_thread ()->control.exception_resume_breakpoint == NULL' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.
Quit this debugging session? (y or n) FAIL: gdb.gdb/python-selftest.exp: call
catch_command_errors(execute_command, "python print 5", 0, RETURN_MASK_ALL)
(GDB internal error)
