Bug description: Segmentation fault when build as extension
I recently compiled PHP with recode support (Version 3.6) without any
problems. But when I compile it as a shared extension, Apache (2.0.44)
fails on startup with a segmentation fault shortly after loading
librecode. Strace shows the following:
gettimeofday({1044530175, 187698}, NULL) = 0
time(NULL) = 1044530175

--- SIGSEGV (Segmentation fault) ---
Unfortunately I can't give you more information because debugging apache
via gdb results in a mysterios infinite loop.
