Hello, For an unknown reason __reclaim_stacks uses a nested function, which is a feature even deprecated in GCC and unsupported in other compilers. This was introduced in a032a6587011cbdac8c2f7e11f15dc4e592bbb55. glibc has meanwhile expanded this inline: https://sourceware.org/git/?p=glibc.git;a=commit;f=nptl/allocatestack.c;h=fc75bf464d128f6a722d6cca7012c996f1f73425 The attached patch moves the function into file scope. Best, Michael
