Teeny test program compiles, links OK with -m32. Compile/link with -m64
yields error as follows:
TestClass.o(.eh_frame+0x30):/usr/local/gcc-3.4.3/lib/gcc/sparc-sun-
solaris2.8/3.4.3/../../../../include/c++/3.4.3/bits/basic_string.h:217:
relocation truncated to fit:
R_SPARC_DISP32 .gnu.linkonce.t._ZN13TestExceptionD1Ev
The problem is resolved when the main program does not throw test exception, or
when TestClass is omitted and main() does throw the exception.
The csh script "build" rebuilds all three files and makes an executable called
bdb. The files are TestException.[cpp,h] a minimal exception class, TestClass.
[cpp,h] a minimal class, and test.cpp - the main program. .ii's included in
the attached tar.bz2 file
Here's the build output:
