--- Comment #3 from Martin Liška <marxin at gcc dot gnu.org> ---
We really end up with the following bogus locations for test_t2:
xloc = expand_location (DECL_SOURCE_LOCATION (current_function_decl));
expanded_location endloc = expand_location (cfun->function_end_locus);
start location:
(gdb) p xloc
$2 = {
file = 0x7fffffffe034 "/home/marxin/Programming/testcases/pr94029.c",
line = 3,
column = 3,
data = 0x0,
sysp = false
}
end location:
(gdb) p endloc
$3 = {
file = 0x7fffffffe034 "/home/marxin/Programming/testcases/pr94029.c",
line = 2,
column = 1,
data = 0x0,
sysp = false
}
So it's probably a C error or linemap error? Here's where we set
cfun->function_end_locus = input_location:
