This is likely a compiler bug. I can think of no other explanation for it: CC -o nsLeakDetector.o -c -DOSTYPE=\"IRIX6\" -DOSARCH=\"IRIX\" -D_IMPL_NS_COM -I../../dist/include/string -I../../dist/include/boehm -I../. ./dist/include/xpcom -I../../dist/include -I/projects/sise/mozilla/devel/workpits/moz/latest_mips/workarea/dist/include/nspr -KPIC -LANG:exceptions=ON -woff 3201 -woff 1506 -mips3 -n32 -woff 3262 -G 4 -n32 -DNDEBUG -DTRIMMED -O2 -DIRIX=1 -DNSCAP_DISABLE_DEBUG_PTR_TYPE S=1 -DD_INO=d_ino -DSTDC_HEADERS=1 -DHAVE_ST_BLKSIZE=1 -DHAVE_SIGINFO_T=1 -DHAVE_INT16_T=1 -DHAVE_INT32_T=1 -DHAVE_INT64_T=1 -DHAVE_UINT=1 - DHAVE_UINT_T=1 -DHAVE_UINT16_T=1 -DHAVE_DIRENT_H=1 -DHAVE_GETOPT_H=1 -DHAVE_MEMORY_H=1 -DHAVE_UNISTD_H=1 -DHAVE_NL_TYPES_H=1 -DHAVE_MALLOC_H =1 -DHAVE_X11_XKBLIB_H=1 -DHAVE_SYS_STATVFS_H=1 -DHAVE_SYS_STATFS_H=1 -DHAVE_SYS_CDEFS_H=1 -DHAVE_LIBM=1 -DHAVE_LIBDL=1 -DHAVE_LIBSOCKET=1 - DFUNCPROTO=15 -DHAVE_XSHM=1 -DHAVE_RANDOM=1 -DHAVE_STRERROR=1 -DHAVE_LCHOWN=1 -DHAVE_FCHMOD=1 -DHAVE_SNPRINTF=1 -DHAVE_MEMMOVE=1 -DHAVE_RINT =1 -DHAVE_NL_LANGINFO=1 -DHAVE_FLOCKFILE=1 -DHAVE_LOCALTIME_R=1 -DHAVE_STRTOK_R=1 -DHAVE_I18N_LC_MESSAGES=1 -DMOZ_DEFAULT_TOOLKIT=\"gtk\" -D MOZ_WIDGET_GTK=1 -DMOZ_ENABLE_XREMOTE=1 -DMOZ_X11=1 -DMOZ_ENABLE_COREXFONTS=1 -DMOZ_EXTRA_X11CONVERTERS=1 -DOJI=1 -DIBMBIDI=1 -DACCESSIBILIT Y=1 -DMOZ_XPINSTALL=1 -DMOZ_JSLOADER=1 -DMOZ_MATHML=1 -DGC_LEAK_DETECTOR=1 -DNS_DISABLE_LOGGING=1 -DMOZ_USER_DIR=\".mozilla\" -DMOZ_XUL=1 -D MOZ_PROFILESHARING=1 -DMOZ_DLL_SUFFIX=\".so\" -DXP_UNIX=1 -DUNIX_ASYNC_DNS=1 -DJS_THREADSAFE=1 -DNS_PRINT_PREVIEW=1 -DNS_PRINTING=1 -DMOZILL A_VERSION=\"1.5a\" -D_MOZILLA_CONFIG_H_ -DMOZILLA_CLIENT ../../../mozilla/xpcom/base/nsLeakDetector.cpp cc-1387 CC: ERROR File = ../../../mozilla/xpcom/base/nsLeakDetector.cpp, Line = 170 No suitable conversion function from "const nsCID" to "unsigned int" exists.

I dont understand why this works! - "Leak Detector", kCLeakDetectorCID, NS_CLEAKDETECTOR_CONTRACTID, nsLeakDetectorConstructor + "Leak Detector",NS_CLEAKDETECTOR_CID , NS_CLEAKDETECTOR_CONTRACTID, nsLeakDetectorConstructor Is the relevant portion. This is with boehm garbage collection enabled, using MipsPro 7.3.1.3m

Added related bug.

Not surprisingly, this works with gcc-2.95.3

Hmmm, this DOES compile with MipsPro 7.4. So, its almost definetly a compiler bug, but what do we do with it? Perhaps we can just close this... I'm not sure. At least there is a record of it now.

Marking this as WFM, as it does work with the 7.4 compilers.
