Bug ID: 85906
Summary: Conditional jump depends on uninitialized value in
write_decimal / write_integer

Severity: normal

Initialize f->format in write_integer
r256034 modified write_integer to use write_decimal. In write_decimal
(write.c:808) the following line
m = f->format == FMT_G ? -1 : f->u.integer.m;
checks format of the fnode struct. write_integer doesn't initialize that member
which results in a valgrind error "conditional jump or move depends on
uninitialized value".
The attached patch simply sets f->format to FMT_NONE in write_integer.
