Package: gdb
Version: 6.8-3
Severity: normal
NOTE: I encountered what is possibly a second bug while assembling
this bug report. If the scripts are run as presented below, gdb
segfaults. It fails as describled below if the gdb commands are
entered manually.
This does not work as expected (stops at i==0 rather than i == 4):
#!/bin/sh
cat <<EOF1 >bug.cc
#include <vector>
int main()
{
int array[] = { 1, 1, 1, 1, 2 };
std::vector<int> vect( 5, 1 );
int i, j;
for (i = 0; i < 5; ++i)
j = array[i] + vect[i];
return j;
}
EOF1
g++ -g bug.cc -o bug
gdb bug <<CMDS1
b 9
condition 1 array[i] != vect[i]
r
p i
CMDS1
# END SCRIPT
Further, if I insert a single blank line, GDB crashes rather than
failing to correctly evaluate the condition:
#!/bin/sh
cat <<EOF2 >bug.cc
#include <vector>
int main()
{
int array[] = { 1, 1, 1, 1, 2 };
std::vector<int> vect( 5, 1 );
int i, j;
for (i = 0; i < 5; ++i)
j = array[i] + vect[i];
return j;
}
EOF2
g++ -g bug.cc -o bug
gdb bug <<CMDS2
b 10
condition 1 array[i] != vect[i]
r
p i
CMDS2
# END SCRIPT
