Bug ID: 15713
Summary: i386_linux_resume calls QUIT -> lock-up
Product: gdb
Version: HEAD
Status: NEW
Severity: normal
Priority: P2
Component: tdep
Assignee: unassigned at sourceware dot org
Reporter: jan.kratochvil at redhat dot com
Target: i386-unknown-linux-gnu
i386_linux_resume calls target_read() which calls QUIT;.
But linux_nat_resume does not expect called linux_ops->to_resume may throw and
in such case it will leave lwp_info as if the inferior resumed. But the real
inferior was not yet resumed by i386_linux_resume.
This leads to lock-up as GDB then tries to stop the inferior which is already
stopped and so no new waitpid event gets generated.
