Nah, it's failing for me too. Looks like changing from %d to %u altered one
of the scanf behaviors. Nope - it's a GCC optimization bug...
$ gcc sscanftest.c -o sscanftest
$ ./sscanftest
' 2.2' is n2 m2 y0 l0 x0 prerc0 f=2 -> 202000000 expected
202000000
' 2.2c' is n2 m2 y0 l3 x0 prerc0 f=3 -> 202000300 expected
202000300
' 2.2c.1' is n2 m2 y0 l3 x1 prerc0 f=4 -> 202000301 expected
202000301
$ gcc -O2 sscanftest.c -o sscanftest
$ ./sscanftest
' 2.2' is n2 m2 y0 l0 x0 prerc0 f=2 -> 202000000 expected
202000000
' 2.2c' is n0 m2 y0 l3 x0 prerc0 f=3 -> 2000300 expected
202000300
' 2.2c.1' is n0 m2 y0 l3 x1 prerc0 f=4 -> 2000301 expected
202000301
on this mini test program:
#define cNV2N(a, b) printf("-> %10u expected %10u\n",
convertNtopVersionToNumber(a), b)
unsigned int convertNtopVersionToNumber(char *versionString) {
/* This one is purely an arbitrary conversion.
*
* But it knows about the version # schemes we've used in the past
* e.g. 2.2c, 2.2.50, 2.2.97, 3.0pre1, 3.0rc1 etc. so that the number
truly is relative
* for numeric testing.
*
* The goal is to get the following converted to ascending numeric order:
*
* 1.3 2.1 2.1.2 2.1.3 2.1.50 2.1.90 2.2 2.2a 2.2b 2.2c 2.2.50 2.2.97
3.0pre1 3.0rc1 3.0
*
* e.g.:
*
* 1.3 103000000
* 2.1 201000000
* 2.1.1 201000001
* 2.1.2 201000002
* 2.1.3 201000003
* 2.1.50 201050000
* 2.1.90 201090000
* 2.2 202000000
* 2.2a 202000100
* 2.2b 202000200
* 2.2c 202000300
* 2.2.50 202050000
* 2.2.90 202090000
* 3.0pre1 299998001
* 3.0rc1 299999001
* 3.0rc2 299999002
* 3.0 300000000
*
* n.m -> nmm000000
* n.m.x -> nmmyyy0xx (if x>=50 yyy=x else xx=x)
* n.ml -> nmm000l00 (where a=1, b=2, etc.)

}
int main(int argc, char *argv[]) {
cNV2N("2.2", 202000000);
cNV2N("2.2c", 202000300);
cNV2N("2.2c.1", 202000301);
}
I'll have to develop a workaround and report the GCC bug.
