Bug ID: 29921
Summary: GDB steps into printf() when including "cstdio"
Product: gdb
Version: 7.10
Status: UNCONFIRMED
Severity: critical
Priority: P2
Component: gdb
Assignee: unassigned at sourceware dot org
Reporter: abdulrahman.mahmoud75 at gmail dot com
Target Milestone: ---
I have noticed that gdb is now able to step into printf function when including
cstdio starting gdb-7.10.
Here is my small app:
#include <cstdio>
int main()
{
printf("test\n");
return 0;
}
when using GDB-7.10 to step in printf the normal behavior that it should stop
at the return line but instead it stops inside the printf function:
"printf (__format=0x409050 "test\n")
at
e:/win64-assert/modeltech/gcc-7.4.0-mingw64vc16/x86_64-w64-mingw32/include/stdio.h:351
351 __builtin_va_list __local_argv; __builtin_va_start( __local_argv,
__format );"
This behavior happens only on Windows.
