Please upgrade to MIPSpro 22.214.171.124m or better.
In MIPSpro C/C++ 7.4 there is a bug in the intrinsic version of memcmp(), which may result in UIC crashing when compiling the Qt Designer. Either upgrade to 7.4.1 or use the libc.so version of memcmp(). To use the libc.so version, comment out the '#pragma intrinsic (memcmp)' line in the file '/usr/include/internal/string_core.h'.
Starting with Qt 3.3 MIPSpro o32 mode is not supported anymore.
