Under SPARC Solaris, libltdl crashes when compiled for the 64-bit
addressing model. I received these words from the ImageMagick
developer who is flushing out 64-bit related bugs:
The bug is in ltdl and may be related to 64-bit or perhaps not. I added
(void) lt_dlopen("tiff.la") as the very first call of convert.c and got
a fault:
detected a multithreaded program
t@1 (l@1) terminated by signal BUS (invalid address alignment)
Current function is rpl_argz_create_sep (optimized)
521 *pargz_len = argz_len;
(/opt/SUNWspro/bin/../WS6U1/bin/sparcv9/dbx) where
current thread: t@1
