[Bug ld/180] New: missing dynamic relocation record

[truk at optonline dot net]

On OpenBSD-current (post 3.5 release) using gcc 2.95.3 or 3.3.2 to build the 
1.3.1 jdk a shared library is created with a missing dynamic relocation record.

The shared library (libjava_g.so) uses strdup and strcpy from libc. The linker 
creates a dynamic relocation record for strdup, but not for strcpy:

$ objdump -R libjava_g.so | grep -e strcpy -e strdup
20004b60 R_386_JUMP_SLOT   strdup

However both strcpy and strdup appear in the dynamic symbol table:

$  objdump -T libjava_g.so | grep -e strcpy -e strdup
00000000      D  *UND*  00000000              strcpy
00000000      D  *UND*  00000000              strdup

Here is the link command with the list of .o files snipped:

-E <sniped o.files> -lverify -lfdlibm.i386 -lgcc -lgcc /usr/lib/crtendS.o

One other thing I noticed was that strcpy is the first undefined symbol lised 
in the dynamic symbol table:
