Assuming you are on amd64: In ./INCLUDE there is a f2c.h file that is not patched (unlike the version of the system libf2c). The result is, that certain data types in libf2c are assumed to be of type int (size=4), and with the unpatched f2c.h file that is actually included when compiling clapack, the same data type is long (8 byte). Hence some data structures assume different sizes within the library and on the callers side resulting in the segfault. Removing the file INCLUDE/f2c.h solves the problem, because then the system f2c.h will be used. (It may also be necessary to remove F2CLIBS/f2c.h, I already deleted the whole directory before testing). Best, Gert
