There are major failures in the lapack 3.1.1 tests with gcc 2.95.3 and in the
full range up to gcc 4.2.1. The problem seems to appear on 32-bit i386, when
the routines chgeqz and zhgeqz are compiled with -O2.

With 2.95.3 I get:

cgd.out:

 Matrix order=    8, type=15, seed=2866, 214,   1,1861, result  5 is 8.389E+06
 Matrix order=   10, type=15, seed= 362, 860,1065,1109, result  5 is 8.389E+06
 Matrix order=   12, type=15, seed=2619,3620,1934,2301, result  5 is 8.389E+06
 Matrix order=   20, type=15, seed=1185,3266, 461, 701, result  5 is 8.389E+06
 CGV drivers:      4 out of   1092 tests failed to pass the threshold

zgd.out:
 Matrix order=    8, type=15, seed=2866, 214,   1,1861, result  5 is 4.504E+15
 Matrix order=   10, type=15, seed= 362, 860,1065,1109, result  5 is 4.504E+15
 Matrix order=   12, type=15, seed=2619,3620,1934,2301, result  5 is 4.504E+15
 Matrix order=   20, type=15, seed=1185,3266, 461, 701, result  5 is 4.504E+15
 ZGV drivers:      4 out of   1092 tests failed to pass the threshold

(notice that the failing cases are the same)


With 4.2.1:
 CGV drivers:     65 out of   1092 tests failed to pass the threshold
 ZGV drivers:     66 out of   1092 tests failed to pass the threshold
