From: "blarsen at redhat dot com" <sourceware-bugzilla@sourceware.org> To: gdb-prs@sourceware.org Subject: [Bug record/29178] New: GDB wont print frame when reverse stepping out of recursive function Date: Wed, 25 May 2022 13:08:03 +0000 [thread overview] Message-ID: <bug-29178-4717@http.sourceware.org/bugzilla/> (raw) https://sourceware.org/bugzilla/show_bug.cgi?id=29178 Bug ID: 29178 Summary: GDB wont print frame when reverse stepping out of recursive function Product: gdb Version: unknown Status: NEW Severity: normal Priority: P2 Component: record Assignee: unassigned at sourceware dot org Reporter: blarsen at redhat dot com Target Milestone: --- GDB won't print the frame information when reverse stepping out of a reverse function, despite printing the information when it enters the functions, or when it leaves non-recursive functions. Reproducer: int factorial(int n){ int result; if(n <= 1) result = 1; result = n * factorial(n - 1); return result; } int main(){ factorial(5); return 0; } And using the following commands: (gdb) start 25 factorial(5); (gdb) record (gdb) n 27 return 0; (gdb) rs factorial (x=5) at 16678.c:10 10 } (gdb) 9 return result; (gdb) 8 else result = x * factorial(x-1); (gdb) factorial (x=4) at 16678.c:10 10 } (gdb) 9 return result; (gdb) 8 else result = x * factorial(x-1); (gdb) factorial (x=3) at 16678.c:10 10 } (gdb) 9 return result; (gdb) 8 else result = x * factorial(x-1); (gdb) factorial (x=2) at 16678.c:10 10 } (gdb) 9 return result; (gdb) 8 else result = x * factorial(x-1); (gdb) factorial (x=1) at 16678.c:10 10 } (gdb) 9 return result; (gdb) 7 if(x <= 1) result = 1; (gdb) 8 else result = x * factorial(x-1); 7 if(x <= 1) result = 1; (gdb) 8 else result = x * factorial(x-1); (gdb) 7 if(x <= 1) result = 1; (gdb) 8 else result = x * factorial(x-1); (gdb) 7 if(x <= 1) result = 1; (gdb) rn 8 else result = x * factorial(x-1); (gdb) 7 if(x <= 1) result = 1; As can be seen, we don't get information about the depth when reverse stepping out. -- You are receiving this mail because: You are on the CC list for the bug.
