I've been using an application (under SunOS 4.1.3) which switches time zones frequently. It has a memory leak which I think I've tracked down to tzload, which I call via tzset. Since it would hardly be noticeable to anyone who didn't happen to be using (or abusing) tzset thousands of times, I wouldn't be surprised if it hadn't been noticed before. On the off chance that someone out there has encountered it, can you send me pointers to patches, workarounds, etc.? I can't switch to Solaris yet. Here are some details: I profile this code: #include <time.h> main() { int i; for (i=0; i<100; i++) { tzset(); } } and find that malloc is called roughly 400 times, while free is called roughly 300 times. If I increase the number of iterations in the loop tp 1000, the calls to malloc and free go up by a factor of 10. malloc is being called from calloc, which is being called from allocall, which is being called from tzload. It looks to me like tzload allocates 4 things and only frees 3 of them each time it is called. Thanks for any help you can give me. Stephen Eubank eubank@predict.com
