This is interesting because I don't get the same failures.

joe at gcc33:~/ltrace$ uname -a
Linux gcc33 2.6.31.12-ER1-efikamx #1 Tue Jan 26 00:57:33 CST 2010
armv7l GNU/Linux

joe at gcc33:~/ltrace$ file ltrace
ltrace: ELF 32-bit LSB executable, ARM, version 1 (SYSV), dynamically
linked (uses shared libs), for GNU/Linux 2.6.16, not stripped

Only failures I get are:

FAIL: func_double(3.40*, -3.40*).*= -3.40* in
/home/joe/ltrace/testsuite/ltrace.main/parameters.ltrace for 0 times
,should be 1
FAIL: <... func_call resumed> \"x\", \"y\") in
/home/joe/ltrace/testsuite/ltrace.main/parameters.ltrace for 0 times
,should be 1

libdl and syscalls both work for me.

Can you ensure that you were building the correct version of the
source? Top of the tree I just built has sha:
ccb0b06787e9132ddf9586148223c6dc0cc3ca20.

Thanks,
