Set default pthread stack size to 8 MB
Set default pthread stack size to 256 KB
This patch tries to fix various crashes for applications depending on
libmilter by setting the stack size for pthreads to 8 MB. The default
stack size for musl libc is set to 80 KB whereas glibc has it set
to 8 MB. This causes problems when a large amount of memory is
allocated on the stack.
This patch tries to fix various crashes for applications depending on libmilter
by setting the stack size for pthreads to 256 KB. The default stack size for
musl libc is set to 80 KB whereas glibc has it set to 8 MB. This causes problems
when a large amount of memory is allocated on the stack.
For example, opendkim allocates blocks of 64 KB multiple times, which
causes libmilter (and therefore opendkim) to crash.
Maybe a stack size of 1 MB or 2 MB would be sufficient, but as opendkim
depends on the default glibc behavior, 8 MB should be safe.
For example, opendkim allocates blocks of 64 KB multiple times, which causes
libmilter (and therefore opendkim) to crash. For now, a stack size of 256 KB
looks sufficient and makes opendkim stop crashing.
