Bug ID: 18060
Summary: eflags.TF left set after exiting from record mode
Product: gdb
Version: HEAD
Status: NEW
Severity: normal
Priority: P2
Component: gdb
Assignee: unassigned at sourceware dot org
Reporter: dje at google dot com
Not sure how I did this, I can't recreate it with toy programs.
I was playing with recording gdb, and after doing "record stop"
I did "continue" and got a SIGTRAP.
It didn't appear to be a case of an int3 left in the instruction stream.
It turned out to be due to eflags.TF being set.

A kernel patch for that bug just made it to the mm tree this week... -- You are receiving this mail because: You are on the CC list for the bug. ^ permalink raw reply [flat|nested] 3+ messages in thread
