30 | -- brobecker/2007-09-06: At the time when this issue (G904-017) was | |
31 | -- reported, the problem only reproduced if the variable was declared | |
32 | -- inside a function (in other words, stored on stack). Although | |
33 | -- the issue probably still existed when I tried moving this variable | |
34 | -- to a package spec, the symptoms inside GDB disappeared. | |
